1. Alternate exterior angles are pairs of congruent angles on opposite sides of the transversal, outside of the space between the parallel lines. In the figure above, there are two pairs of alternate exterior angles: and , and and . 2. Alternate interior angles are pairs of congruent angles...
Vertical Angles When two lines or line segments intersect, two pairs of congruent (equal) angles are created. The angles in each pair of congruent angles created by the intersection of two lines are called vertical angles:In this figure, and are vertical angles (and therefore congruent), as a...

(called the vertex of the angle). The measure of an angle is how far you must rotate one of the rays such that it coincides with the other. In this guide and for the Math IC, you don’t really need to bother with such a technical definition. Suffice it to say, angles are used ...
