Question 1

1 / -0

Match the columns:

1. A rectangle in which two adjacent sides have equal length is a	a. rhombus
2. If the diagonals are perpendicular to each other and the opposite corner angles are equal to each other, then the parallelogram is a/an	b. rectangle
3. A parallelogram whose diagonals are congruent is a	c. square
4. The two non-parallel sides are equal and form equal angles at one of the bases, then it is called a/an	d. isosceles trapezium

Solution

1. A rectangle in which two adjacent sides have equal length is a square.

2. If the diagonals are perpendicular to each other, then the parallelogram is a rhombus.
These are the properties of a rhombus.

1. The diagonals are perpendicular to each other.
2. Opposite angles are equal.

3. A rectangle has the following properties:

All the properties of a parallelogram apply (the ones that matter here are parallel sides, opposite sides are congruent, and diagonals bisect each other).
All angles are right angles by definition.
The diagonals are congruent.

4. It's a property of an isosceles trapezium that the two non-parallel sides are equal and form equal angles at one of the bases.
