Math Problem Statement
Solution
Let’s analyze the given table and solve the properties of each quadrilateral.
(a) Parallelogram
- Four right angles: No. A parallelogram doesn’t necessarily have right angles unless it is a rectangle or square.
- Two pairs of parallel sides: Yes. By definition, a parallelogram always has two pairs of parallel sides.
- Only one pair of parallel sides: No. A parallelogram always has two pairs of parallel sides.
- All sides congruent: No. A parallelogram doesn’t require all sides to be congruent unless it is a rhombus or square.
Correct options for parallelogram: Two pairs of parallel sides.
(b) Rhombus
- Four right angles: No. A rhombus does not require right angles unless it is a square.
- Two pairs of parallel sides: Yes. A rhombus is a type of parallelogram, so it always has two pairs of parallel sides.
- Only one pair of parallel sides: No. A rhombus has two pairs of parallel sides.
- All sides congruent: Yes. By definition, all sides of a rhombus are congruent.
Correct options for rhombus: Two pairs of parallel sides, All sides congruent.
(c) Rectangle
- Four right angles: Yes. By definition, a rectangle always has four right angles.
- Two pairs of parallel sides: Yes. A rectangle is a type of parallelogram, so it always has two pairs of parallel sides.
- Only one pair of parallel sides: No. A rectangle has two pairs of parallel sides.
- All sides congruent: No. A rectangle doesn’t require all sides to be congruent unless it is a square.
Correct options for rectangle: Four right angles, Two pairs of parallel sides.
Final Summary:
Quadrilateral | Four Right Angles | Two Pairs of Parallel Sides | Only One Pair of Parallel Sides | All Sides Congruent |
---|---|---|---|---|
Parallelogram | ✔ | |||
Rhombus | ✔ | ✔ | ||
Rectangle | ✔ | ✔ |
