Question 1 of 3

Two lines intersect. One angle measures 47°. What is the measure of the angle directly across from it (the vertically opposite angle)?

Question 2 of 3

Two lines intersect. One angle measures 57°. What is the measure of the angle opposite to it (vertically opposite angle)?

Question 3 of 3

Two lines intersect. One angle measures 48°. What is the measure of the angle opposite to it (the vertical angle)?

How this fits in

Angle relationships is one skill in the Basic Geometry unit. Students read the unit lesson, then earn a bronze, silver, or gold medal on their last 10 answers. Medals never go down. A mastered unit comes back for review after 1, 3, 7, 16, and 35 days so it stays learned.
