Should we assume that angles E,F,G, and H are right angles if they are the four corners...?

If they are the four corners of a rectangle, and why?

Yes. That is the definition of a rectangle.

If it is a rectangle then the four corners are right angles(90 degrees). Reason the word 'Rectangle' means 'four right angles'.
A quadrilateral is a four sided figure, but it is not necessary for all the angles to be right angles. eg. an asymmetric trapezium.

Cause a square or a rectangle, has or is made up of four right angles.
