Answer:
1. True
2. False
3. True
4. True
5. True
Step-by-step explanation:
1. Properties of a square,the diagonals are congruent.
2. For rectangles, parallelograms, trapeziums the diagonals are not perpendicular.
3.In any rhombus, the diagonals (lines linking opposite corners) bisect each other at right angles (90°). That is, each diagonal cuts the other into two equal parts, and the angle where they cross is always 90 degrees.
4.All squares are rhombuses, but not all rhombuses are squares.
5.If both pairs of opposite angles of a quadrilateral are congruent, then the quadrilateral is a parallelogram. If the diagonals of a quadrilateral bisect each other, then the quadrilateral is a parallelogram. If a quadrilateral is a rectangle, then it is a parallelogram.
