Equilateral triangles have all sides of equal length. In turn, that means all angles have equal measure. Congruency in Isosceles and Equilateral Triangles That relationship can be used to solve algebraic expressions. 2x + 10 = 60 - 10 -10 2x = 50 2 x = 25 2 Isosceles triangles have two sidesof equal length. In turn, that meansthe angles opposite those equalsides have equal measure. Congruency in Isosceles and Equilateral Triangles That relationship can be used to solve algebraic expressions. vertex angle = 180 - 72 - 72 = 36 base angles 8y - 16 = 72 + 16 +16 2y = 88 9x = 36 9 2 y = 44 x = 4 9 2 Here are some isosceles and equilateral triangles.
