      A triangle is equilateral if and only if it is equiangular. Each angle of an equilateral triangle measures 60 °. Definition: The perimeter of a triangle is the sum of the lengths of all of its sides. Example: In the figure below, PQ ≅PR , and PS and ST are medians. Find QT and QR. 1 Example: KL is an altitude of ∆HJK . Find x. (3x + 21) °

      Isosceles Triangle Theorem (or the Equilateral Triangle Theorem), students should construct an isosceles (or equilateral) triangle and measure the angles. As students drag the vertices of the triangle to change its size or shape, the individual base angle measures will change (for isosceles only), but the relationship between

      Isosceles, Equilateral, and Right Triangles Isosceles Triangles In an isosceles triangle, the angles across from the congruent sides are congruent. Also the sides across from congruent angles are congruent. Example 1) Find the value of x and y. Solution: Since triangle BDC is isosceles, then the angles opposite the congruent sides are congruent.

      Use isosceles and equilateral triangles. Using the Base Angles Theorem 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.
