A triangle is shown with its exterior angles. The interior angles of the triangle are angles 2, 3, 5. The exterior angle at angle 2 is angle 1. The exterior angle at angle 3 is angle 4. The exterior angle at angle 5 is angle 6.
A
m∠5 + m∠6 = m∠1B
m∠3 + m∠4 + m∠5 = 180°C
m∠1 + m∠2 = 180°D
m∠2 + m∠3 = m∠525
