Because angle 3 forms a vertical pair with the angle marked 7x 3˚, 80˚ = 7x 3˚, so x = 11˚. example 3 find the measure of the acute alternate interior angles. parallel lines mean that alternate interior angles are equal, so 5x 28˚=2x 46˚! 3x=18˚! x=6˚. use either algebraic angle measure: 2(6˚) 46˚=58˚ for the measure of the acute. These relationships include a comparison of the position, measurement, and congruence between two or more angles. congruent angles no matter their orientation all have equal measures. adjacent angles are when two lines cross each other; they form four angles. any two angles are sharing a ray, line segment, or line.
