A.1.Name a pair of complementary angles.

2.Name two pairs of supplementary angles.

3.Nmae the pairs of adjacent angles.

4.Name the linear pairs of angles.

5.m∠ABE+m∠CBD=₋₋₋₋₋degrees

6.if ∠ABE≅∠CBD,then m∠ABE+m∠EBD=₋₋₋₋₋₋₋degrees.




B.determine whether each statement is true or false

1.vertical angles are two nonadjacent angles formed by a pair of intersecting lines.

2.two angles are vertical angles if their sides form two pairs of opposite rays.

3.when two intersect,they form four pairs of vertical angles.

4.vertical angles formed by two intersecting lines are coplanar.


C.1.if ∠A and ∠b are complementary,what is the sum of their measures?
