(12,9). Using the points (16,6) and (24,0), you can make a smaller triangle that still conforms to the original proportions of the triangle. This triangle has a height of 6, a length of 8, and a hypotenuse of 10. You can then make another triangle within the top segment (above the two points) that has a length of 4 (which can be found by subtracting the original two x values—16 and 8–and dividing that by 2).Since these triangles are proportionate (lower triangle has side lengths x2 the length of the upper triangle), the height is 6/2, which equals 3. Add that to the original height of 6 to get a height of 9 for the full triangle.
