Part A Mark the focus of the parabola you are going to create at F(6,4). Draw a horizontal line that is 6 units below the focus. This line
will be the directrix of your parabola. What is the equation of the line?

Use pythagorean’s theorem and find the missing side lengths of the two smaller triangles and add them together
13^2 - 12^2 = 5
15^2 - 12^2 = 9
5+9 = 14
14 is the length of each side of the square
14^2 + 14^2 = 19.8
19.8 is the diagonal length of the inside if the square
