Draw one triangle with an area of 12 square units. Try to draw a non-right triangle.
Explain how you know the area of your triangle is 12 square units.
Here are three copies of the same triangle. The triangle is rotated so that the side chosen as the base is at the bottom and is horizontal. Draw a height that corresponds to each base.
Draw a line segment to show the height for the chosen base in each triangle.
For this triangle, identify and label a base and height. If needed, draw a line segment to show the height. Find the area of this triangle. Show or explain your reasoning. (The side length of each square on the grid is 1 unit.)
