ISOSCELES AND EQUILATERAL TRIANGLES WORKSHEET GEOMETRY PDF

The examples of the isosceles are the golden triangle, isosceles right triangles, and the faces of bipyramids as well as certain Catalan solids.Įquilateral - This is a triangle that has all three sides equal or of the same length. You can find the other two isosceles triangles if you have one interior angle. These isosceles shapes are used in regular polygon areas plus, the triangles are called 45-45-90. The congruent sides are called legs from the vertex angle, and the other two are base angles. Isosceles - Suppose two sides of a triangle are congruent, the angles that are opposite are congruent. What Are Equilateral and Isosceles Triangles? When it comes to angles of triangles: acute (all angles are acute), right (one right angle), obtuse (one obtuse angle), and equiangulars (you guessed it have all equal angles). If all sides are equal it is called equilateral. The Isosceles Triangle Theorem tells us that if you have an isosceles triangle the angles opposite the congruent sides are also congruent. If two sides of a triangle are congruent that are considered the same in all respects.

If the length of two sides of the triangle are equal it is called isosceles. If all the lengths of their sides are different it is scalene.
