Triangles don't exist. ... But triangles are like Santa Claus, the tooth fairy, and Beyoncé: too strange and perfect to exist in the actual world. By definition, a triangle is a two-dimensional figure (perfectly flat) with three sides (perfectly straight) meeting at three vertices (perfectly sharp).

Answer and Explanation: No, not all right triangles are isosceles. Although it is possible to have a right triangle that is an isosceles triangle, not all right triangles...

In the familiar Euclidean geometry, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°. It is also a regular polygon, so it is also referred to as a regular triangle.

Any triangle whose sides are in the ratio 3:4:5 is a right triangle. Such triangles that have their sides in the ratio of whole numbers are called Pythagorean Triples. ... If you multiply the sides by any number, the result will still be a right triangle whose sides are in the ratio 3:4:5.

When two of the faces meet, they form a line segment called an edge. When three edges meet, they form a point, which is called a vertex (the plural of vertex is vertices). A triangular prism has 5 faces, 9 edges, and 6 vertices.

On a rectangular prism, each rectangular side is congruent (the same size) with the another one parallel to it. On a triangular prism, three of the sides are rectangles, and two of them are triangles. At least two of the rectangles are congruent, and the two triangles are also congruent.

An equiangular triangle is a kind of acute triangle, and is always equilateral. In a right triangle, one of the angles is a right angle—an angle of 90 degrees. A right triangle may be isosceles or scalene.

A right triangle is a triangle in which one angle is a right angle. The relation between the sides and angles of a right triangle is the basis for trigonometry. The side opposite the right angle is called the hypotenuse (side c in the figure). The sides adjacent to the right angle are called legs (sides a and b ).

An equilateral triangle is one with three equal sides. An isosceles triangle is one with two equal sides. Therefore, every equilateral triangle is isosceles, but not every isosceles triangle is equilateral.

Additionally, an equilateral triangle not only has three congruent sides, but also three congruent angles all measuring 60 degrees. Likewise, an equilateral triangle is also an acute triangle.

for base on sides,triangles are three types, equilateral,isosceles and scalene. For based on angles, Triangles are three types, acute angled triangle, right angles triangle and obtuse angled triangle.

There are different names for the types of triangles. A triangle's type depends on the length of its sides and the size of its angles (corners). There are three types of triangle based on the length of the sides: equilateral, isosceles, and scalene.

Isosceles triangles are triangles with two equal sides, and thus two equal angle measures. For example, both of these triangles are isosceles, since they have two equal sides and angles. ... However, since they don't have corresponding congruent angles ( 75∘≠45∘ ), these triangles are not similar.

An isosceles triangle has two lengths which are the same as each other, and two angles which are the same as each other. An equilateral triangle has three equal lengths, and all the angles are equal which means they are each 60°. A scalene triangle has three different length sides, and three different angles.

It is possible to construct an isosceles triangle of given dimensions using just a compass and straightedge. See these three constructions: Isosceles triangle, given base and side. Isosceles triangle, given base and altitude.
