what does equilangular mean?
94712
Well it does mean that all the angles are of equal measure. and from what KIMBERLY said shes wrong its not in Algebra 1 that you learn that its supposed to be Geometry.

This refers to the idea in Evolution that new species form very quickly, then things remain more or less unchanged for a relatively long period of time.\n\nThis is used to explain the lack of "missing links".  If the changes occur very quickly, and then everything returns to "normal" (hence the equilibrium), then there should be very few transitional species, or missing links.

equal number of sides and equal measure of angles\n\n\nor at least thats what i remember from geometry!

Let the triangle be ABC\n\nAB = BC\n\nso angle C = angle A (opposite angle of equal sides)\n\nAB = CA\nso angle C = angle B\n\nso all angles are same\nso equiangular

it means that as a (linear) transformation from the plane to the plane it reverses the orientation.\nthe way we calculate the area, is really a signed area, in the sense that it takes into consideration the orientation of the 2 vectors.\nit is a bit subtle and that is why most teachers do not really explain it.\n'

except balance????? what do you mean? equilibrium is the central point of balance

In an equilateral traingle, all sides are equal and all three angles are 60 degrees.\n\nIn an isosceles triangle, two sides are equal and the two base angles of an isosceles triangle are equal to one another.\n\nThe other answer above refers to light reflected in a mirror or other reflecting surface/

a rectangle, by definition is a quadrilateral where all four angles are right-angles, and an oblong is that which is right angled but not equilateral. I know its a bit obscure, but really, an oblong is an old fashioned term for a rectangle, without equilateral sides, if that's possible?!\n\nhope it helps

A equilateral triangle has rotational symmetry because there is a center point that you can rotate it about such that it will have the same positional appearance three times.  You need to rotate it one third of a circle to get each identical view.\n\nThere should be infinitesimal degrees of rotation for a circle such that it will still appear to be a circle.  You could move a point on its circumference to any other point on the circle and it will still be a circle.  I guess you knew that.

Square- four equal, parallel sides, all right angles\nRectangle-four parallel sides, not necessarily all equal, with four right angles\nTrapezoid- one pair of parallel sides\nRhombus- all sides parallel, but not at right angles

if it is equilateral i, it is also equiangular so all angels equal 60 degrees...\nso solve 19x + 3=60sub that in to ...23y-3x = 60 for x and solve for y and sub y into 5y + z = 60 and solve for z

that is possibel only if your triangle abc is equilateral or isosceles. otherwise, that wouldn't happen:)

For an object to be in mechanical equlibrium, the forces acting on it must be zero per standard definition.\n\nHowever, there is a good, short discussion on this topic in Wikipedia, the free, online encyclopedia:\n\nhttp://en.wikipedia.org/wiki/Mechanical_equilibrium\n\nQuoting:\n"A standard definition of mechanical equilibrium is:\n    A system is in mechanical equilibrium when the sum of the forces, and torque, on each particle of the system is zero.\n\nA particle in mechanical equilibrium is neither undergoing linear nor rotational acceleration; however it could be translating or rotating at a constant velocity.\n\nHowever, this definition is of little use in continuum mechanics, for which the idea of a particle is foreign. In addition, this definition gives no information as to one of the most important and interesting aspects of equilibrium states – their stability.\n\nAn alternative definition of equilibrium that is more general and often more useful is\n    A system is in mechanical equilibrium if its position in configuration space is a point at which the gradient of the potential energy is zero. "\n\nHope this helps!

I'm not familiar with that one.  I know a circle as a "set of points all equidistant from a fixed point in a plane".\n\nI see where you are going with your definition, but I don't think it is worded well.  For one, it doesn't specify that these direction-changing lines are pivoting around a fixed point.  They could just be scattered all over the plane in which case, since they are infinite, you'd end up with a shaded in plane instead of a circle.  For another, they would need to be line segments instead of lines, and the endpoint would be what is creating the closed loop.  And which point on the line segment would they be pivoting around?  If it's one endpoint, then the line seg. would be the radius; if the midpoint, diameter.  Any other point on the line segment would create 2 circles.

The first thing is to understand the difference between similar and congruent (identical).  Two triangles are similar if their shapes are similar, but their sizes may be different.  An equilateral triangle is similar to another equilateral triangle, but one could have sides of length 1 and the other sides of length 2.  These are *similar*.  But for them to be congruent both their angles and their sides would all have to be the same.\n\nLike you said, if two triangles had 2 angles the same (and therefore the 3rd angle must be known to be the same since they all add up to 180), then you've only proven them *similar*.  A side could be 3 units long, but if you doubled them all, you would still have a *similar* triangle, but it wouldn't be *congruent*.\n\nA concept commonly taught in high school mathematics is that of proving the "angle" and "side" theorems, which can be used to define two triangles as similar or congruent.\n\nIn each of these three-letter acronyms, A stands for equal angles, and S for equal sides. For example, ASA refers to an angle, side and angle that are all equal and adjacent, in that order.\n\nAAA - Angle-Angle-Angle. If two triangles share three common angles, they are *similar*. (Obviously, this means that the side lengths are locked in a common ratio, but can vary proportionally, making the triangles similar.) Additionally, since the interior angles of a triangle have a sum of 180°, having two triangles with only two common angles (sometimes known as AA) implies similarity as well. \n\nTwo triangles are *congruent* if their corresponding sides and angles are equal. Usually it is sufficient to establish the equality of three corresponding parts and use one of the following results to conclude the congruence of the two triangles:\n\nSAS (Side-Angle-Side): Two triangles are *congruent* if a pair of corresponding sides and the included angle are equal.\n\nSSS (Side-Side-Side): Two triangles are *congruent* if their corresponding sides are equal.\n\nASA (Angle-Side-Angle): Two triangles are *congruent* if a pair of corresponding angles and the included side are equal.\n\nWhile the AAS (Angle-Angle-Side) condition also guarantees *congruence*, SSA (Side-Side-Angle) does not, as there are often two dissimilar triangles with a pair of corresponding sides and a non-included angle equal. This is known as the ambiguous case. Of course, AAA (Angle-Angle-Angle) says nothing about the size of the two triangles and hence shows only *similarity* and not congruence.\n\nHowever, a special case of the SSA condition is the HL (Hypotenuse-Leg) condition. This is true because all right triangles (which this condition is used with) have a congruent angle (the right angle). If the hypotenuse and a certain leg of a triangle are congruent to the corresponding hypotenuse and leg of a different triangle, the two triangles are congruent.
