If you get stuck, carefully consider which side of the triangle to use as the base.
Problem 4
Can side
![A triangle with sides labeled d, e, and f. The angle opposite side D is a right angle. A segment labeled g is perpendicular to side d and extends to the opposite vertex.](../../../../../../embeds/7870b0e2--6.1.C.PP.New.Image.10.png)
Problem 5 From Unit 1 Lesson 3
Find the area of this shape. Show your reasoning.
![A shape with six sides. There are two vertical sides measuring five units, two angled sides that fall 2 units over 4 units and two sides that fall 2 units over 2 units.](../../../../../../embeds/4078de0c--6.1.A.PP.New.Image.18a.png)
Problem 6 From Unit 1 Lesson 6
On the grid, sketch two different parallelograms that have equal area. Label a base and height of each and explain how you know the areas are the same.
