Point

Something that has no size and names a location; dot.

Line Segment

A piece of a line that has been cut into a certain distance

Plane

A flat surface that extends forever

Angle

The space in between two line segments or lines.

Perpendicular lines

Two lines that intersect, that make four angles and all four angles made by the intersecting lines

measure Ninety Degrees.

Parallel lines

Two lines that run side by side and never intersect no matter how far they go in either direction.

Triangle

A three sided Polygon.Regular triangles have three 60 degree angles.

Right Triangle

A triangle that has one right (90 degrees) angle.

Pentagon

A polygon that has 5 sides.

Hexagon

A polygon that has 6 sides.

Square

A four sided polygon.A square has all sides same length and all angles on

a square are 90 degrees.

Rectangle

A square that has four 90 degree angles but all four sides do not have to be the same length.

A square is a rectangle but a rectangle isn’t a square.

Trapezoid

Like a rectangle but all angles don’t have to be 90 degrees.

A rectangle is a trapezoid but a trapezoid is not a rectangle.

A square is a trapezoid but a trapezoid id not a square.

Parallelagram

Like a Trapezoid but the sides must be parallel.Ex. Left must be parallel to Right and Top must be parallel

to Bottom.Square is a parallelogram but a parallelogram is not a

square.A rectangle is a parallelogram but a parallelogram is not a

rectangle.

Circle

A line that is the same distance in every direction from one point inside the plane

that the circle is in. The point is in the direct middle of the

circle.

Cylinder

A circle that has height.

Sphere

A three dimensional circle.

Cube

A three dimensional square.

Triangular Pyramid

A pyramid with a triangle as a base.

Square Pyramid

A pyramid with a square as a base.
