This video tutorial explains how to use triangle congruence to identify measures of corresponding sides and angles in triangles. Defines side-side-side (SSS) postulate.

Explains the relationship between the measures of angles formed when parallel lines are cut by a transversal based on relationships of corresponding, vertical, and supplementary angles. [7:53]

Identifies which angles are congruent when parallel lines are cut by a transversal. [7:07]

Identifies and defines the types of angles formed by parallel lines cut by a transversal and the relationship of their measures. Discusses Triangle Sum Theorem. [9:48]

Proof by contradiction that corresponding angle equivalence implies parallel lines.

This lesson [5:22] will demonstrate how to prove lines parallel with the converse of the corresponding angles postulate. It is 6 of 6 in the series titled "Corresponding Angles Converse."

This lesson will demonstrate how to prove lines parallel with the converse of the corresponding angles postulate. It is 1 of 6 in the series titled "Corresponding Angles Converse." [2:37]

From this lesson, you'll see that that when a transversal crosses two parallel lines, corresponding angles are congruent.
