What do you call two angles whose measures have a sum of?
What are the angle pair relationships?
Definition: The pairs of opposite angles formed by two intersecting lines are called vertical angles. For example, in the diagram on the right, 21 and 23 are a pair of vertical angles, and 22 and 24 are a pair of vertical angles.
What pairs of angles are formed by two intersecting lines?
Supplementary angles are two angles whose sum is equal to 180∘. In other words when you add the measure of one angle in the pair with the other angle in the pair, they equal 180 degrees.
Vertical Angles. Step-by-step explanation: Vertical angles are two nonadjacent angles formed by two intersecting lines.
When the sum of the measures of two angles is 1800 the angles are called?
Supplementary angles are two angles whose measures add up to 180° . The two angles of a linear pair , like ∠1 and ∠2 in the figure below, are always supplementary.
