Square Meter

The square meter is the basic unit of area of the Metric System.

Area is length by length, so:

A square that is 1 meter on each side
is 1 square meter.

The Unit is meters × meters, which is written m² (square meters).

You could have other shapes (such as a rectangle that is ½ a meter by 2 meters) that also make 1 square meter.

Example: How big is this rectangle?

It is 2 meters by 3 meters, so it is 2 m × 3 m = 6 m²

congruent triangles

What is "Congruent" ... ?

It means that one shape can become another using Turns, Flips and/or Slides:

Rotation		Turn!
Reflection		Flip!
Translation		Slide!

Congruent Triangles

          When two triangles are congruent they will have exactly the same three sides and exactly the same three angles.
         The equal sides and angles may not be in the same position (if there is a turn or a flip), but they are there.
