Area Blocks (Triangle)

 Drag unit squares and pieces of unit squares to find the area of a triangle. Rotate or reflect pieces using the transformation box on the right side of the screen. Stamp a shape and reuse the same pieces. Similar apps with different features are also available from EDC in Maine, including Area Blocks (5 Figures), which has 5 figures to fill and can be used to create your own figures, and Area Blocks (5 Figures & Rectangle), which has the same 5 figures and also has an optional resizable rectangle to help find the areas of the figures.
