100
This is represented by a straight path that extends in two opposite directions without end and has no thickness.
What is a line?
100
This is a point that divides the segment into two congruent segments.
What is a midpoint?
100
This angle measures less than 90 degrees.
What is an acute angle?
100

This is a line that cuts two or more parallel lines.

What is a transversal?

100

These are polygons with fives sides.

What is a pentagon?

200
This is represented by a flat surface that extends without end and has no thickness.
What is a plane?
200

These are two lines that intersect at a right angle.

What is perpendicular?

200

These are two angles that share a common side and vertex.

What are adjacent angles?

200

These are two angles whose sum is 180 degrees.

What are supplementary angles?

200

These are triangles that have two congruent sides and two congruent angles.

What are isosceles triangles?

300

This is part of a line that consists of two endpoints and all points between them.

What is a line segment?

300
This is formed by two rays with the same endpoint.
What is an angle?
300

These angles add up to 90 degrees.

What are complementary angles?

300

These are angles on opposite sides of the transversal and outside the parallel lines.

What are alternate exterior angles?

300

These are triangles that have all of the same side lengths and angles.

What are congruent triangles?

400

This is part of a line that consists of one endpoint and all the points of the line on one side of the endpoint.

What is a ray?

400
This is the endpoint of the angle.
What is the vertex?
400

This angle measures 180 degrees.

What is a straight angle?

400

These are two angles that are in matching corners or the transversal. "copy and paste"

What are corresponding angles?

400

These are quadrilaterals with congruent diagonals.

What is a rectangle?

500

These are two points that lie on the same plane.

What is coplanar?

500
This is a ray that divides an angle into two congruent angles.
What is an angle bisector?
500

These are two angles directly across from each other on intersecting lines.

What are vertical angles?

500

These are angles that are on the same side of the transversal and inside the parallel lines.

What are consecutive interior angles?

500
This is the quadrilateral that is the most specific.

What is a square?
