For each triangle, a base is labeled
Select all triangles that have an area of 8 square units. Explain how you know.
5 triangles on grid labeled A, B, C, D, E. A base = 4, height = 4. B base = 4, height = 4. C base = 3, height = 5. D base = 4, height = 4. E base = 8, height = 2.
Find the area of the triangle. Show your reasoning.
If you get stuck, carefully consider which side of the triangle to use as the base.
Can Side
Find the area of this shape. Show your reasoning.
On the grid, sketch two different parallelograms that have equal area. Label a base and height of each and explain how you know that the areas are the same.
