Area of Triangles Exploration

Without measuring or calculating, predict how the area of each triangle will compare to the group. Which triangle will have the largest area? Which triangle will have the smallest area? Will any of the triangles have the same area?

Now using the area formula for a triangle and the coordinate grid, how the area of each triangle will compare to the group. Which triangle has the largest area? Which triangle has the smallest area? Do any of the triangles have the same area?
