Question

1. choose true or false.

two angles that share a common vertex and one common side but have no common interior points are vertical angles.
false
true

1. choose true or false.

two angles in which the sum of their measures is 180° are supplementary angles.
false
true

Explanation:

Question 9

Vertical angles are formed by two intersecting lines and are opposite each other, sharing a common vertex but not a common side. The description here matches adjacent angles (sharing a vertex and side with no common interior points). So the statement is false.

By definition, supplementary angles are two angles whose measures add up to \(180^\circ\). So the statement matches the definition.

Answer:

False
