Angles
Refer to the diagram below and answer each question

Name a pair of alternate interior angles (using 3 letters for each name) and state their measures (Example: <KLM = 67 deg and <XWV = 56 deg )

Name a pair of corresponding angles (using 3 letters for each name) and state their measures

Name a pair of same side (consecutive) interior angles (using 3 letters for each name) and state their measures

Use your mouse to drag points A, B, C, and (or) D to make the two lines parallel to each other. (Remember what we said about the slopes of parallel lines! Use the grid to count rise and run.)
