What do we call a part of a line containing two endpoints and all the points between?

• a line

• a ray

• a line segment

• a plane

If two angles are supplementary ......

• they form a right angle

• they add to 180°

• they add to 90°

• they are adjacent

What do you call the common endpoint of two rays? 

• Angle

• Segment

• Ray

• Vertex 

Two angles that add to 90^o are _________ angles.

• complementary angles

• right angles

• vertical angles

• supplementary angles

An angle bisector.......

• Cuts and angle into two angles

• Cuts a segment in half

• Cuts and angle into two congruent angles

• Creates an angle

Perpendicular lines ........

• intersect each other

• never cross

• create an 'X'

• intersect to form right angles

The midpoint of a line segment ......

• Cuts the segment into two congruent segments

• Splits the segment into two pieces

• Is a line that goes through the segment

• Is half the segment

If two lines are parallel .......

• they never intersect

• they create an 'X'

• the meet at a common point

• the form right angles

What do we call a portion of a line that extends from one point infinitely in one direction?

• a line

• a ray

• a line segment

• a plane

Adjacent angles......

• overlap each other

• share a vertex and overlap each other

• share a vertex and a common side but do not overlap each other

• are across from each other
