## Geometry: Common Core (15th Edition)

We use elimination but we first have to determine the measure of the quadrilateral's angles: $90^{\circ}$. F is false because we cannot state that the side's length is the same and a rectangle does not have congruent sides. G is false because the angles are right, not acute. H is true because it is a rectangle so the sides are parallel. I is false because we cannot state that the rectangle is a square.
