Isosceles Triangle Theorem
In an isosceles triangle, the base angles are congruent.
Vertical Angles Theorem
Vertical Angles are congruent.
Alternate Interior Angles Theorem
If the lines are parallel, the alternate interior angles are congruent.
Triangle Sum Theorem
The sum of the measures of the angles of a triangle is 180 degrees.
Third Angle Theorem
If two angles in one triangle are congruent to two angles in another triangle, the third angles are congruent.
Congruent and Supplementary Theorem
If two angles are congruent and supplementary, then each is a right angle.
Supplements of Congruent Angles Theorem
Supplements of Congruent angles are congruent.
Right Angles are Congruent Theorem
All right angles are congruent.
Converse of the AIA Theorem
If two lines are cut by a transversal forming congruent alternate interior angles, then the lines are parallel.
AEA Theorem
If two parallel lines are cut by a transversal, then the alternate exterior angles are congruent.
Converse of the AEA Theorem
If two lines are cut by a transversal forming congruent alternate exterior angles, then the lines are parallel.
Interior Supplements Theorem
If two parallel lines are cut by a transversal, then the interior angles on the same side of the transversal are supplementary.
Converse of the Interior Supplements Theorem
If two lines are cut by a transversal forming interior angles on the same side of the transversal that are supplementary, then the lines are parallel.
SAA Congruence Theorem
If two angles and the non-included side of one triangle are congruent to two angles and the non-included side of another triangle, then the triangles are congruent.
