Proving Lines Parallel
Show it can all be proved. Scholars learn the converses of the properties of parallel lines. Using the converses, pupils determine which lines are parallel based on angle measurements and practice using a flow proof to show that two...
Flipped Math
Properties of Parallel Lines
Work within a parallel universe. Scholars learn about the relationships of angles when two parallel lines are intersected by a transversal. They see how to find the measurements of all eight angles by knowing the measure of one angle....

Vertically Opposite Angles
How can opposites be equal? Pupils learn about the measures of angles when two lines intersect by watching an educational video. They see how vertical angles are congruent, and solve problems using this idea.
