What appears to be true about the diagonals of a trapezoid? They are congruent.

30. Open-Ended Point B(-3, -3) is the endpoint of many segments.

a. Find the coordinates of the midpoint and the other endpoint of four

noncollinear segments that have point B as their endpoint.

b. You know that a segment with endpoint B lies entirely in Quadrant III.

What does that tell you about the other endpoint?

c. How many possible segments parallel to either the y-axis or the x-axis

match this description? Explain.
