The base angles theorem states that if the sides of a triangle are congruent (Isosceles triangle)then the angles opposite these sides are congruent.
Statement 1: An isosceles triangle's altitude, or line segment that extends from the triangle's apex to its base's midpoint, is perpendicular to its base. This part of the theorem is true because an isosceles triangle's congruent sides place its apex (point A) directly over the base's midpoint (point D). So when we draw the altitude, it creates a straight line that intersects the base at a right angle.
