Look at the two triangles below:
Angle B is equal to angle E.
Angle A is equal to angle D.
Which angle corresponds to angle C?
As we have two pairs of corresponding angles, we will use the angle-angle theorem for triangle similarity.
Now that we know all angles are equal to each other, we note that the remaining angle that is equal and corresponds to angle C is angle F.
Angle B is equal to 60°
Angle C is equal to 55°
Angle E is equal to 60°
Angle F is equal to 50°
