1. Draw a coordinate plane.

2. Use the origin as vertex W of the triangle WXZ.

3. Place the base of the triangle along the positive x- axis.

4. Position the triangle in the first quadrant.

5. Since X is on the x-axis, its y-coordinate is 0.

     Its x-coordinate is because each side has length units.

6. Triangle WXZ is an equilateral triangle, so the x-coordinate of Z is halfway between 0 and    that is .

7.Since is an equilateral triangle, y-coordinate of Z is  units.
