Constructing Angles
Draw a pair of vertical angles with a measure of 40°.
Step 1: Use a protractor to draw a 40° angle.
Step 2: Use a straightedge to extend the
sides to form two intersecting lines.
PRACTICE:
Tell whether the angles are adjacent or vertical. Then find the value of x.
Draw a pair of vertical angles with the given measure.
40
75
120
