Line l and line m are straight lines. Line l and m intersect with a third line to form 5 angles. From top left, clockwise, the angles are b, 90 degrees, c, 124 degrees, a. Which statements are true regarding the angles in the figure? Select two options. Measure of angle a = measure of angle b Measure of angle a = measure of angle c Measure of angle a + measure of angle b = measure of angle c Measure of angle a + measure of angle b = 90 degrees
