Answer:

bisect each other.

Step-by-step explanation:

The midpoints are the same point, so the diagonals bisect each other.

<em>More elaboration on a proof</em>

The alternate interior angles formed by diagonals and the sides of the triangle are congruent, so the (point-to-point) triangles formed by the crossing diagonals are congruent ASA. Since the sides of those triangles are congruent, the diagonals meet at their midpoints. That is, the diagonals bisect each other.

Hello!

When doing a 90 degree reparation you flip the coordinates and apply to the sign of the quadrant.

For example, If it flips into quadrant one, they will both be positive.

So, in this case it would be Triangle 4.

Hope this helped!
