Does it say the diagonals intersect at their midpoints?

[bobsmith76]

I can't imagine how it's possible that the diagonals are equal and form a right triangle and they NOT intersect at the midpoint.

[I like Serena]

Trapezoid?

Try to draw 2 line segments of equal length and perpendicular.
And make them not intersect in the middle.
What's the resulting quadrilateral?

Same idea as I like Serena:

Start with a square and draw it diagonals. Now erase the square, leaving only the diagonals. Now erase about half of each diagonal above the point where they intersect. Of what figure are they the diagonals?

Thanks, I got it.
