In this geometry lesson you will learn about isosceles and equilateral triangles. you will also see the converse of the isosceles triangle theorem, equiangu. 5.4 equilateral and isosceles triangles 245 example 2 finding measures in a triangle find the measures of ∠p, ∠q, and ∠r. solution the diagram shows that pqr is equilateral. so, by the corollary to the base angles theorem, pqr is equiangular. so, m∠p = m∠q = m∠r. 3(m∠p) = 180° triangle sum theorem m∠p = 60° divide each side by 3. •understand the properties of isosceles and equilateral triangles. •use the base angles theorem and its converse. •prove an equilateral triangle is also equiangular. Using properties of isosceles triangles a triangle is an isosceles if it has at least two congruent sides. if it has exactly two congruent sides, then they are the legs of the triangle and the non congruent side is the base. the two angles adjacent to the base are the base angles. the angle opposite the base is the vertex angle. base angles.
