What is the criteria for shapes to be similar?

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

Because of the ratio of area inside a shape compared to the outline isnt the most efficient (outline 4a cf area a^2) where a is the length of side for the square (rationalises to 4:a)\n\none would find other shapes to be more efficient like hexagons, with circles having the best ration between area and circumference (PI*d cf (PI*d^2)/2) which rationalises to 1:d/2 where d is the diameter (width) of the circle.\n\nthe circle will contain the maximum area within for the minimum circumference thus rendering it cheaper if you are say making a box for a known quantity of goods.\n\nother than that the answer can depend on what the final calculations are to be used for

almost the same\n\n:> peace

I asked that same question to my teacher last time. She told me that I have to Seperated the shape into different common shapes. (for example like lets say I wanted to seperate a "square" into some common shapes I could turn it into two seperate triangles or four different triangles. Well Just try to use the formulas you know for the areas of the different disected figures you get.

I don't believe it can.  This is an example of a unicursal problem and you can find some more details at the puzzle link in the reference below, you'll need to scroll down to puzzle number 51.\n\nFrom my days of O Level Maths I remember that we touched on these and I seem to recall that there was an equation to do with the number of vertices and nodes that a shape had which would determine if it was unicursal or not.\n\nBasically only unicursal shapes (those with a specific ratio of nodes and vertices) can be drawn without removing a pencil from the page and without tracing over an existing line.\n\nI'll leave further research to you.\n\nHave fun

this is impossible to answer, there are many shapes that could be made this way.  do you have any other information like right angles or angles at corners?

since your ddoing coordinate geometry you should at least tell what shape you're trying to get.\nI'm assuming it's a parallelogram so u should make it (1,8)

You're best bet is to think of them as an assembly of right angle parrellelagrams. Then each parrellelagram has a volumn of base x height x width. If they are not of that shape think of them as of that shape anyway.

a cone-shaped object would be described as 'conical'\n\nEveryday objects of this shape:\n\nIce cream cone\nCertain wine stoppers\nSome seeding devices for the garden\nPlant food distributors\nIncence cones\nParty Hats\nCentral part of a lemon juicer

There are different formulas for different shapes. This page has a list of them: http://www.math.com/tables/geometry/volumes.htm

It's been too long for me.\n\nSample many definitions. Go to MATHWORLD.COM (lower case)\n2 geometric figures are CONGRUENT when one gets transformed into the other by isometry.\n\nStay with it.\n\nGRIZZ

Congruent.  \n\nComplementary angles are angles whose sum is 90˚.  So for an angle to be complementary to another anlge, it must equal 90˚ minus the size of the other angle.  If to two angles are complimentary to the same angle, they both equal 90˚ minus the size of that other angle, and since that other angle doesn't change, the sizes of the two angles must be equal, which means they're congruent.\n\nA few people have said the angles are "equal."  While they have the right idea, angles actually have no numerical value, and therefore can't be equal to each other.  The correct term for geometic objects (like angles) that have the same size and shape (i.e. are "equal") is congruent.

It all depends on what the shape the object is.

Assuming you mean as 4 shapes equivalent to the original L shape, the answer is given in the attached image.

Isomorphic if you are in abstract algebra.\n\nCongruent if you are in geometry.

polygons are 2 dimensional shapes. they must have all straight sides and they must be closed. some examples are squares triangles, etc.  circles aren't because they  have 1 curved side.\n\npolyhedrons are 3-d shapes that have all flat sides and have no openings. ex: cube. spheres, cones, and cylinders are not because they all have curved sides.

a regular polygon has the same angles and sides while a irregular one has different sides and angles.
