1. Draw a coordinate plane.
2. Use the origin as vertex M of the triangle MNP.
3. Place the base of the triangle along the positive x- axis.
4. Position the triangle in the first quadrant.
5. Since N is on the x-axis, its y-coordinate is 0.
Its x-coordinate is 2a because each side has length 2a units.
6. Triangle MNP is an equilateral triangle, so the x-coordinate of P is halfway between 0 and
2a that is .
7.Since is an equilateral triangle, y-coordinate of E is 2a units.
The graph is
