Answer:
3. A parallelogram with one right angle is a rectangle. A quadrilateral whose diagonals are equal and bisect each other is a rectangle.
4. Rhombus Theorem: A quadrilateral is a rhombus if and only if it has four congruent sides. Square Theorem: A quadrilateral is a square if and only if it has four right angles and four congruent sides. From the Square Theorem, we can also conclude that a square is a rectangle and a rhombus.
5. A square is a four-sided figure with equal sides and four right angles. All squares are Rhombus and rectangles. Rhombus because the four sides have the same length and rectangle because it has four right angles.
