Front

Who am I? I am a part of a line with two endpoints. I have a definite length.

Back

Line segment

Front

Who am I? I am two lines that are always the same distance apart. I never meet, no matter how far you extend me.

Back

Parallel

Front

Who am I? I am two lines that intersect to form right angles. I meet at a 90-degree angle.

Back

Perpendicular

Front

Who am I? I am an exact location in space. I have no size, only position.

Back

Point

Front

Who am I? I am a part of a line that starts at a point and extends infinitely in one direction. I have one endpoint.

Back

Ray

Front

Who am I? I am a line that divides a shape into two equal parts. Each part is a mirror image of the other.

Back

Symmetry

Front

Who am I? I am the space between two intersecting lines or surfaces. I am measured in degrees.

Back

Angle

Front

Who am I? I am a point where two or more lines meet. I am often found at the corners of polygons.

Back

Vertex

Front

Who am I? I am a closed figure with three or more straight sides. Examples of me include triangles, quadrilaterals, and pentagons.

Back

Polygon

Front

Who am I? I am a round shape with all points the same distance from the center. I have a radius and a diameter.
