Exterior Angles Theorem

Oct 27­8:21 PM

4.2 Apply Congruence and Triangles

1. In triangle ABC, if measure of angle A = 64 degrees and the measure of angle B = 71 degrees, what is the measure of angle C?

2. What property of angle congruence is illustrated by this statement?If    A           B and      B         C, then    A        C.

Oct 27­8:22 PM

Pick out the congruent figures.

Corresponding Angles

Triangle Congruence Statement 

Proving two triangles are congruent with 6 statements

Oct 27­9:03 PM

Just given this statement, determine the corresponding sides and angles.

Corresponding Sides

 

Corresponding Angles

JKL  =      MNO

Oct 27­9:05 PM

Triangle Congruence Statement

Corresponding Angles

Corresponding Sides 

Are these two triangles congruent?

If so, prove that they are.

Oct 27­9:08 PM

Third Angle Theorem: if two angles of one triangle are congruent to two angles of another triangle, then the third angles are also congruent.
