Angle Pairs

When two lines intersect, they form four angles that go all the way around the intersecting point, so the sum of their measures is 360°

Intersecting Lines

Angle Pairs

 

Adjacent angles are supplementary because they form a straight angle.

 

 

 

 

 

 

 

 

 

 

 

 

 

Vertical angles are each of the pairs of opposite angles made by two intersecting lines. Vertical angles are congruent.
