Geometry

A _ is part of a line. It has two endpoints, which are marked with a point.

• line segment

• line

• angle

• ray

A _ is a straight path. It doesn't have any end points. It goes on forever (infinite).

• endpoint

• ray

• angle

• line

An _ is formed when two line segments or rays meet at an end point.

• ray

• angle

• line segment

• vertex

A _ is also part of line, but it goes on forever in only one direction. It has only one endpoint.

• line segment

• vertex

• ray

• endpoint

Has no height, length or width. It is

an exact location.

• ray

• vertex

• point

• congruent

Either of two points marking the

end of a line segment.

• polygon

• point

• ray

• endpoint

The point where two lines, line

segments, or rays form an angle.

• endpoint

• angle

• congruent

• vertex

when they have EXACTLY the

same three sides and EXACTLY

the same three angles.

• vertex

• infinite

• congruent

• polygons

When they don’t have exactly the

same sides and or the same

angles.

• infinite

• pentagon

• non congruent

• quadrilateral

All sides are straight, No

intersecting lines, No Curves (closed figure, straight sides)

• congruent

• polygons

• vertex

• lines
