Vertical angles are 2 angles that are directly ​ (a)   from each other when 2 lines cross, and they are ​ (b)   ​ (c)   .

Supplementary angles add up to be ​ (d)   degrees, and they don't have to be next to each other.

Complementary angles add up to be ​ (e)   degrees, and they don't have to next to each other.

Adjacent angles are two angles that share a common ​ (a)   and a common (b)   . They are next to each other.

A linear pair are two ​ (c)   angles that form a straight line. They are always ​ (d)   , adding to 180 degrees.

A trasversal is a ​ (e)   that crosses two or more other lines.

Corresponding angles are angles in the same ​ (a)   , like ​ (b)   , and they are only ​ (c)   if the two lines are parallel​ .

Angles 3 and 7 are corresponding angles, and so are angles 2 and ​ (d)   , and angles 1 and ​ (e)   .
