Look at the two triangles below:
Angle B is equal to angle F.
Angle C is equal to angle D.
Which angle corresponds to angle A?
We use the angle-angle theorem to simulate triangles.
Let's observe the data we already have:
Angles B and F are equal.
Angle C is equal to angle D.
Therefore, the remaining angles must also be equal: angles A and E.
Angle B is equal to 60°
Angle C is equal to 55°
Angle E is equal to 60°
Angle F is equal to 50°
