Move point C so that ∠BAC and ∠CAD form a pair of supplementary angles, or angles whose sum is 180°. Record each of the angle measurements for this case.

Sagot :

The recorded angle measurements of ∠BAC and ∠CAD could be 110° and 70°, vice versa.

What are supplementary angles?

Supplementary angles are a pair of angles that always sum up to 180°. These angles can either;

  • adjacent  
  • non-adjacent.

Adjacent supplementary angles

Adjacent supplementary are angles with a common vertex and arm.

Non-adjacent supplementary angles

Non- adjacent supplementary angles are angles without a common vertex or arm.

∠BAC and ∠CAD are adjacent supplementary angles because they have a common vertex, A, and a common arm AC.

They add up to 180°.

∠ BAC = 110° and ∠CAD = 70°

Hence, the angles could be 110° and 70°.
