Is this a circle? Why or why not?

No, it is not. Is this a circle? It does not have points that are the same distance from the centre point.

What is a Circle? A shape made up of points that are the same distance from the centre point.

Vocabulary Centre Diameter Radius Circumference

Centre The centre is in the middle of the circle.

Radius A radius is a line from the center of a circle to the outer edge.

Diameter Diameter is a line in a circle that goes through the centre and has endpoints on the circle.

Circumference Circumference is the distance around a circle.

How to Draw a Circle Use a compass
