Which of the following quadrilaterals has two pairs of adjacent sides ...
Key Concepts:
- Quadrilaterals are polygons with four sides.
- A square is a quadrilateral with four equal sides and four right angles.
- A rhombus is a quadrilateral with four equal sides, but the angles are not necessarily right angles.
- A kite is a quadrilateral with two pairs of adjacent sides equal, but the angles are not necessarily right angles.
- A rectangle is a quadrilateral with four right angles, but the sides are not necessarily equal.
Explanation:
To determine which quadrilateral has two pairs of adjacent sides equal and diagonals intersecting at right angles, we need to analyze the properties of each quadrilateral: square, rhombus, kite, and rectangle.
Square:
- A square has four equal sides and four right angles.
- The diagonals of a square intersect at right angles.
- Therefore, a square satisfies the given conditions.
Rhombus:
- A rhombus has four equal sides, but the angles are not necessarily right angles.
- The diagonals of a rhombus intersect at non-right angles.
- Therefore, a rhombus does not satisfy the given conditions.
Kite:
- A kite has two pairs of adjacent sides equal, but the angles are not necessarily right angles.
- The diagonals of a kite intersect at non-right angles.
- Therefore, a kite does not satisfy the given conditions.
Rectangle:
- A rectangle has four right angles, but the sides are not necessarily equal.
- The diagonals of a rectangle intersect at right angles.
- Therefore, a rectangle satisfies the given conditions.
Conclusion:
Based on the analysis above, the quadrilateral that has two pairs of adjacent sides equal and diagonals intersecting at right angles is a square.

Sum of all exterior angles of a regular polygon =360 .So number of sides here =360÷45=8.
