Answer 1

Answer:

1. Rhombus has all its sides equal and so does a square. Also, the diagonals of the square are perpendicular to each other and bisect the opposite angles. Therefore, a square is a type of rhombus......
2. Show that if the diagonals of a quadrilateral bisect each other at right angles, then it is a rhombus. Sol: We have a quadrilateral ABCD such that the diagonals AC and BD bisect each other at right angles at O. Their corresponding parts are equal. Thus, the quadrilateral ABCD is a rhombus......

3.A quadrilateral with the opposite side lines parallel is known as a parallelogram. If only one pair of opposite sides is required to be parallel, the shape is a trapezoid. UK

4.A rectangle is a quadrilateral in which all angles are right angles. A rectangle is a parallelogram, so its opposite sides are equal. The diagonals of a rectangle are equal and bisect each other.....

5.rhombus

If two adjacent sides of a parallelogram are equal, then it is a rhombus. This test is often taken as the definition of a rhombus. A quadrilateral whose diagonals bisect each other at right angles is a rhombus......
