100

This represents a location, but has no size.

What is a point?

100
The midpoint for the points (4,2) and (-3,-5).
What is (0.5,-1.5)?
100

The endpoint of an angle or where the two rays meet.

What is the vertex?

100
Lines AB and DE intersect at point C. Ray CF is an angle bisector of angle BCE and angle BCF equals 20 degrees. This is the measure of angle ACD.
What is 40 degrees?
100
If angle CFD is congruent to angle EFD, then ray FD is this.
What is an angle bisector?
200

This is named using any two points; goes in both directions forever.

What is a line.

200

The midpoint for (4,1) and (-2,-1).

What is (1,0)?

200
Angles that have the same measure.
What are congruent angles?
200
Angles ABC and CBD form a pair of complementary angles. B is the midpoint of line CF and angle CBD measures 18 degrees. This is the measure of angle ABF.
What is 108 degrees?
200
If the measure of angle AFC is 120 degrees, and angle AFC is supplementary to angle AFB, the measure of angle AFB is this.
What is 60 degrees?
300

This is named using three points; has infinite length and width.

What is a plane?

300

The midpoint for (3,2) and (-5,1).

What is (-1,1.5)?

300

This divides an angle into two congruent angles starting from the angle's vertex.

What is an angle bisector?

300

Angles ABC and CBF form a pair of complementary angles. B is the midpoint of line CD and angle CBF measures 18 degrees. This is the measure of angle DBF.

What is 162 degrees?

300

What is the definition of an acute angle?

What is an angle whose measure is less than 90 degrees?

400

This divides a line segment into two congruent segments.

What is a midpoint?

400

The midpoint between (5,2) and (3,-1).

What is (4,0.5)?

400

Two angles whose measurements add up to 90 degrees.

What are complementary angles?

400

Lines AB and DE intersect at point C. Ray CF is an angle bisector of angle BCE and angle BCF equals 15 degrees. This is the measure of angle BCD.

What is 150 degrees?

400

True or False: If a segment intersects another segment, it bisects it.

What is false?

500

This begins at a point and extends infinitely in one direction.

What is a ray?

500
The midpoint between (2,5) and (3,-5).
What is (2.5,0)?
500

Two angles whose measurements add up to 180 degrees.

What are supplementary angles?

500

Through any two points, this many number of lines can be drawn.

What is one?

500
If ray BD bisects the right angle ABC, then angle ABD measures this.
What is 45 degrees?
