Web11. jan 2024. · The Isosceles Triangle Theorem states: If two sides of a triangle are congruent, then angles opposite those sides are congruent. To mathematically prove this, we need to introduce a median line, a line constructed from an interior angle to the midpoint of the opposite side. We find Point C on base UK and construct line segment DC:
