- Textbook:

A quadrilateral with exactly one pair of parallel sides.

PENTAGON

- Man–Made: The shape of this house illustrates a pentagon.

- Natural: The top shell of this big turtles have different shapes of pentagons in a pattern.

- Textbook:

A figure with five sides and five angles.

HEXAGON

- Man–Made: This metal fence follows the pattern of an hexagon shape.

- Natural: A beehive forms the shape of many little hexagons.

- Textbook:

A figure with six sides and six angles.

CIRCLE

- Textbook:

- Man–Made: A plate illustrates an example of a circle.

- Natural: This circular opening in the ground is probably the home of some animal.

A closed, curved two dimensional figure. All the points on the circle are the same distance from the center.

RADIUS (CIRCLES)

- Man–Made: A street drain illustrates the radius of a circle.

- Natural: By looking at Sindy’s eye we can see the radius of her pupil.

- Textbook:

The radius is a line segment joining the center to any point on the circle.

TANGENT

- Man–Made: A battery on top of a table represents a tangent line.

- Natural: A vine grapes can also represent a tangent line.

- Textbook:

A tangent is tangent line is a straight line that touches a function at only one point.

CHORD

- Man–Made: This sign shows a chord with a line across to keep out people from smoking in that area.

- Natural: This cross section photo of a tree shows a line joining two points of the trunk.

- Textbook:

A line segment joining two point on a circle.

SPHERE

- Textbook:

- Man–Made: A basket ball is a good example of a sphere

- Natural: An orange follows the shape of a sphere.
