1-75.

Examine the diagrams below. For each pair of angles marked on the diagram, quickly decide what angle pair relationship(s) the angles have. You may list more than one relationship for each pair of angles.

  1. ​An isosceles triangle where the base line is extended to the right outside of the triangle. The interior angle is labeled a and the exterior angle is labeled b.

    linear pair or straight angle pair, supplementary

  1. A triangle where two of the sides are extended outside of the triangle. The interior angle is labeled c and the angle opposite is labeled d.

  1. A right triangle where the 90 degree angle is split into two angles f and g.

    These angles add to degrees.

  1. An isosceles triangle with the two base angles labeled h and k.

    These angles are equal in measure.
