Explore & Practice Angles Between Two Lines and a Transversal

Explore the app below and learn the special names of the angles formed by two lines and , intersected by a transversal . Drag the green points and explore the special relationship between those angles, when the two lines cut by the transversal are parallel. NOTICE what happens when you make the lines PARALLEL!

Answer the following questions...



Two parallel lines are cut by a transversal. A same side (consecutive) interior angle of a pair measures 45°. What is the measure of the other same side interior angle of the pair? (ONLY 1 is correct!)
