First, use a unit circle to determine the end points of the chord on the circle.
If each endpoint on the chord is connected to the cen... | 677.169 | 1 |
The diagonals divide the quadrilateral into four sections. You
can then use the bisection to prove that opposite triangles are
congruent (SAS). That can then enable you to show that the
alternate angles at the ends of the diagonal are equal and that
shows one pair of sides is parallel. Repeat the process with the
other... | 677.169 | 1 |
