Key concepts
3 concepts
- 1
Same side interior angles are located on the inside of two parallel lines and on the same side of the transversal.
- 2
Same side interior angles add up to 180 degrees.
- 3
To solve for a missing angle or variable, set up an equation where the sum of the two same side interior angles equals 180 and then solve the equation.

11 questions
What is the relationship between same side interior angles formed by two parallel lines cut by a transversal?
If two parallel lines are cut by a transversal, and one of the same side interior angles measures 110°, what is the measure of the other angle?

Quick comprehension check
“Two parallel lines are cut by a transversal. Two interior angles on the same side of the transversal measure 110° and (5x + 10)°. Solve for x.”
