Congruency in Isosceles and Equilateral Triangles
Contributed by: Potter
Equilateral triangles have all sides
of equal length. In turn, that means
all angles have equal measure.

That relationship can be used to
solve algebraic expressions.
2x + 10 = 60
      - 10  -10
2x = 50

Isosceles triangles have two sidesof equal length. In turn, that meansthe angles opposite those equalsides have equal measure.

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
