Question

Draw another 20 by 20 grid. Draw four points for a rectangle and then draw a fifth point to add right triangle to its side in order to form a composite figure of a trapezoid. List the coordinates of the five points.

Answer 1

Let's create a 20 by 20 grid and define the coordinates of the five points that form a rectangle and a triangle to form a trapezoid.

1. **Rectangle Points:**
- Point A: \((5, 5)\)
- Point B: \((5, 10)\)
- Point C: \((10, 10)\)
- Point D: \((10, 5)\)

2. **Triangle Point:**
- Point E: \((12, 10)\)

The composite figure formed will have a rectangle with points A, B, C, and D, and a right triangle with the right angle at point C, extending to point E.

### Coordinates of the points:
- Point A: \((5, 5)\)
- Point B: \((5, 10)\)
- Point C: \((10, 10)\)
- Point D: \((10, 5)\)
- Point E: \((12, 10)\)

This setup forms a trapezoid with the rectangle on one side and the right triangle on the other.
