When a transversal intersects with two parallel lines eight angles are produced.
The eight angles will together form four pairs of corresponding angles.
we have the measure of angle 8=23°
angle 2=angle 4 =angle 6 =angle 8=23°
we have a supplementary formed by angle 1 and angle 2
angle 1 + angle 2=180°
angle 1 + 23=180
angle 1= 180-23
angle 1=157
angle 1= angle 3 = angle 5 = angle 7 =157°
a. angle 1 157°
b. angle 2 23°
c. angle 3 157°
d. angle 4 23°
e. angle 5 157°
f. angle 6 23°
g. angle 7 157°
the angles in red are equals to 23
the angles in blue are equals to 157
