How to Find Missing Angles Using Angle Relationships
Professor Kat
Guided Notes
Key concepts students will learn:
- •
When two parallel lines are cut by a transversal, there are relationships between the angles formed, such as alternate interior angles and corresponding angles.
- •
Supplementary angles form a straight line and their measures add up to 180 degrees.
- •
Alternate interior angles are congruent, meaning they have the same measure.

“In the diagram below, lines m and n are parallel. Find the measures of angles x and y. Show your work. [Diagram: Two parallel lines, m and n, are intersected by a transversal. One angle is labeled 70°. Angle x is an alternate interior angle to the 70° angle. Angle y is on the same side of the transversal as the 70° angle and forms a straight line with it.]”
