A triangle is shown with its exterior angles. Angles 2, 6, and 4 are the interior angles. Angle 1 is the exterior angle at angle 2. Angle 5 is the exterior angle at angle 6. Angle 3 is the exterior angle at angle 4.

Which statements are always true regarding the diagram? Check all that apply.

m∠3 + m∠4 = 180°

m∠2 + m∠4 + m∠6 = 180°

m∠2 + m∠4 = m∠5

m∠1 + m∠2 = 90°

m∠4 + m∠6 = m∠2

m∠2 + m∠6 = m∠5
