100
An angle that measures less than 90°.
What is acute angles?
100
Links to two points without extending beyond them.
What is a line?
100
The distance between two points.
What is length?
100
Two rays with a common endpoint that point in opposite directions and form a straight line.
What is opposite rays?
100
The angle formed when one side is extended beyond its adjacent sides.
What is exterior?
200
A ray that divides an angle into two angles that are congruent.
What is a angle bisector?
200
Links two points without extending beyond them.
What is a line segment?
200
The shortest length between two points.
What is distance?
200
Two nonparallel lines in space that do not intersect.
What is a skew line?
200
The angle formed inside it by any two adjacent sides of the polygon.
What is interior?
300
Two angles with a common vertex and side but no common interior points.
What is adjacent angles?
300
We identify this with a number or letter, this has no width or length to it, it just pecifies an exact location.
What is a point?
300
The point half way between a line segment.
What is the midpoint?
300
A line or a ray or a segment that divides a line segment into two equal parts.
What is a segment bisector?
300
Three or more points that lie on the same straight line.
What is collinear?
400
if two angles add up to 180°.
What is supplementary angles?
400
This has an end point and goes on in one direction.
What is a ray?
400
to divide into two equal sections, or a half.
What is bisect?
400
A point at which the arms (sides) of an angle meet.
What is vertex?
400
Has the same shape but not necessarily the same size.
What is similar?
500
180° angles.
What is straight angles.
500
When two lines or rays share a same point. Often forms a 90 degree angle.
What is intersecting?
500
When three points are on a line, one is in the middle of the two.
What is between?
500
A flat surface that extends into infinity in all directions.
What is a plane?
500
A set of points, lines, line segments, rays or any other geometrical shapes that lie on the same plane.
What is coplanar?
