Angle 3 is 63° because angle 1 and angle 3 are vertical angles.
Vertical angles are formed when two lines intersect, and they are always equal in measure. Since angle 1 is 63°, angle 3, being its vertical angle, is also 63°.
igure to answer the question.
Two intersecting lines form an x and have four angles at the point of intersection labeled clockwise from the top: 1, 2, 3, and 4.
If angle 1 in the picture is 63° , what is the measure of angle 3? Why?
