interior angle
Angles 3, 4, 5, and 6 are interior angles. Angles 3 and 6 are alternate interior angles, as are angles 4 and 5.

What do the interior angles of a square add up to in degrees?
The interior angles follow the pattern (n--2)(180[degrees])/n, where n is the number of sides.
For example, regardless of the types of quadrilaterals, their interior angles always add to 360[degrees].
Since m[angle]DPQ = m[angle]PQR, (because trapezium PQC'D' is a reflection of trapezium PQCD along the line segment PQ) and m[angle]DPQ = m[angle]RPQ (because alternate interior angles are congruent when a transversals intersects two parallel lines), APQR is an isosceles triangle with m[angle]PQR = m[angle]RPQ.

The quadrilateral's interior angles always add up to 360
