Two angles that are congruent are (sometimes, always, or never) complementary to the same angle. The angles could be obtuse or right and therefore, have no complement.

Two angles that are complementary to the same angle are (sometimes, always or never) congruent.

Two angles that are vertical are (sometimes, always, or never) nonadjacent.

Two angles that are nonadjacent are (sometimes, always , or never) vertical.

Two angles that are complementary (sometimes, always, never) form a right angle. Ambiguous. They always add up to 90 degrees, but they may be 2 separate nonadjacent angles.

Two angles that form a right angle are (sometimes, always, never) complementary.

Two angles that form a linear pair are (sometimes, always, never) congruent. Only 90 degree linear pairs are congruent.

Two angles that are supplementary are (sometimes, always, never) congruent. Only if the angles are 90 degrees each

Two angles that are supplementary are (sometimes, always , never) complementary.

Two right angles are (sometimes, always, never) supplementary.

Vertical angles are (sometimes, always, never) complementary.

Angles with a common side and a common vertex (sometimes, always, never) form a linear pair. True only when their sum is 180. Two acute angles could have a common side and a common vertex and not form a linear pair.


Thanks in advance for the help guys!!!
