# Parallelogram to Cube

Part 1

- Watch the video about folding a parallelogram again and fold a second parallelogram.
- Given the two angle measures shown, what are the measures of the other angles in the parallelogram?

### Part 2

- The parallelograms can be assembled to form a cube. You need six parallelograms, so either make four more or combine yours with two other students’ to get six parallelograms.
- Watch the second video to see how the cube is constructed. Think about the angles involved in changing the two-dimensional figures into surfaces for a three-dimensional figure.
- Make 5–6 cubes if you want to use them in the Zooming in on Shapes unit.
