Shapes in our everyday world!

Shapes are everywhere! A few basic shaped include a rectangle, circle, triangle and octagon. There are many more than just these four but in this lesson we will focus on how often you see these four shapes!

1) A RECTANGLE is a 4 sided figure with 4 right angles. The sides are not all the same length, the two sides parallel to each other are the same length and the other 2 parallel sides are also the same length. If all the sides were the same, it would be a square.
A window in an example of a rectangle we see everyday!

2) A CIRCLE is a shape with a set of points in a plane that are a given distance from a given point (the center of the circle).

 A tire is an example of a circle we see everyday!

3) A triangle is a 3 sided figure with 3 corners or vertices.

The peak of a house is a triangle we see everyday!

4) An OCTAGON is a polygon with 8 sides of the same length and 8 angles the same size.

A stop sign is an example of an octagon we see everyday!

 I hope you learned a lot about four of the basic shapes we see each and every day and next your outside, see how many shapes you can find!
