Definition:
AA:
If two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.
Description:
Given that
To Prove:
If two lines are perpendicular, then they form a right angle. Hence, the angles G and J are right angles.
It is known that all right angles are congruent. So that
If two angles are vertical angles, then they are congruent. That is,
