The length of the segment DF is (x - h), the length of the segment EF is (y - k), and the length of the segment DE is 'r' which is the radius of the circle and this can be determined by using the given data.
Given:
To derive the standard formula of a circle, a radius r is constructed as the hypotenuse of a right triangle as shown.
Right-angled triangle:
The following steps can be used in order to determine the lengths of the sides of the right triangle that is formed:
- Step 1 - The given coordinates of the right triangle are D(h,k), and E(x,y).
- Step 2 - The length of the segment DF is (x - h).
- Step 3 - The length of the segment EF is (y - k).
- Step 4 - The length of the segment DE is 'r' which is the radius of the circle.
Therefore, the correct options are D) and G).
