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
Measure of angle a + measure of angle b + measure of angle c = 124 degrees
