The two obvious vertices are at (0,0) for A, and (0,a) for B.

Point C is at a distance from the x-axis and this distance will be the altitude size from point C to the point ( a/2, 0 ). This altitude cuts the triangle into two special 30-60-90 triangles.

Either of these special triangles has hypotenuse a, leg a/2, and you can find the size of the other leg, the altitude of the equilateral triangle. Call this size, y.

Solve for y.
You will want the PLUS square root form.
Your point C will be, whatever you find for y, C (a/2, y).
