Two intersecting lines create four angles, numbered 1, 2, 3, and 4, where ∠4 is adjacent to ∠1 and ∠3 , and m∠2=110° . Which other angle has a measure that is also equal to 110°
Since ∠2 has a measure of 110°, ∠1 and ∠3 must also each have a measure of 110° because they are adjacent angles and the two intersecting lines create a straight angle. Therefore, ∠4 is the only other angle with a measure of 110°.
