WORK MUST BE SHOWN IN ORDER TO RECEIVE CREDIT. 14. The legs of an isosceles right triangle are 5 inches long. What is the length of
Definitions: An isosceles triangle is a triangle having at least two congruent (of equal length) sides. The two sides are called the legs and the third side is called the base. The point at which the legs meet is the vertex and the angle there is the vertex angle.

Examining Triangles Here are some examples showing the link between the length of a triangle’s sides and its angles. The other two angles in an isosceles triangle are opposite equal sides, so they are equal. Above, J= Land D= F. • MN is the longest side, so O, which is opposite MN, is the largest angle. • BC is the shortest side, so A, which
Isosceles Triangle Theorems Worksheet Five Pack. In 1. ABC, AB = BC AC Is this isosceles triangle or not? ≠. In EBD, the vertices have coordinates E(2,-1), B(0,1), D(2,3). Show whether this. 2. triangle is isosceles or not isosceles. 3. In RST, < R:< S:< T is 3:1:2; is this triangle is isosceles triangle? 4.
A triangle is isosceles when it has at least two congruent sides. When an isosceles triangle has exactly two congruent sides, these two sides are the legs. The angle formed by the legs is the vertex angle. The third side is the base of the isosceles triangle. The two angles adjacent to the base are called base angles. GO DIGITAL Vocabulary
What Are Equilateral and Isosceles Triangles? Isosceles - Suppose two sides of a triangle are congruent, the angles that are opposite are congruent. The congruent sides are called legs from the vertex angle, and the other two are base angles.
