For each triangle, a base is labeled \(b\). Draw a line segment that shows its corresponding height. Use an index card to help you draw a straight line.
Select all triangles that have an area of 8 square units. Explain how you know.
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 \(d\) be the base for this triangle? If so, which length would be the corresponding height? If not, explain why not.
