Triangle Sum Theorem
The theorem that states that the measures of the angles in a triangle add up to 180 degrees.
Third Angle Theorem
If 2 angles of 1 triangle are congruent to 2 angles of a second triangle then the third angles of the triangles are congruent
Two triangles are congruent if 2 sets of corresponding sides and their included angles are congruent.
Two triangles are congruent if 2 sets of corresponding angles and one set on non-included sides are congruent.
Two triangles are congruent if 2 sets of corresponding angles and their included side are congruent.
If you use a congruence shortcut, (SSS,SAS,ASA,AAS) to show that 2 triangles are congruent, then you can use this to show that any of their corresponding parts are congruent
Base Angles Theorem
if two sides of a triangle are congruent, then the angles opposite them are congruent
Converse of the Base Angles Theorem
If two angles of a triangle are congruent, then the sides opposite them are congruent.
