Angles of measure 50° and 150° are supplementary angles.

The complement of the complement of an angle is the angle itself.

If two parallel lines are cut by a transversal, the angles enclosed in Z shape are called alternate interior angles.

The sum of measures of all the angles formed at a point is four right angles.

If two lines intersect at a point, then all pairs of adjacent angles are supplementary.

Two angles making a linear pair are always adjacent angles.

Angles of measure 35° and 55° are supplementary angles.

Adjacent angles of measure 45° and 135° are Linear pair.

Adjacent angles have common interior points.

An angle measures 10° more than its supplement. What is the measure of the angle?

If two supplementary angles are such that one is three times the other, what is the measure of the greater of the two angles?

What is the difference between the supplement of 150° and the complement of 60°?

What is the supplement of the complement of 15°?

If a transversal is perpendicular to one of the two parallel lines, then what angle does it make with the other line?
