Discover the Area of a Triangle

The area of a triangle, like other polygons, is determined by finding out how many unit squares it takes to cover the shape. But what if we don’t want to simply sit and count using a grid or by moving a unit square around on a rectangle? Is there another way? For this activity, you are going to construct different triangles and have GeoGebra compute their area in unit squares. Then you will try to find a pattern in your data.
