Answer:

  • The friend is not correct

Step-by-step explanation:

Side measures is not sufficient to state the figure is rectangle.

It could be a parallelogram too.

To ensure it is rectangle you need to measure the diagonals as well. The diagonals should be equal, then the four formed triangles will be congruent.
