Quadrilateral Definition (MCQ on Quadrilaterals)

A Quadrilateral is known to be a plane figure which has four sides or edges, it also has four corners or vertices. Quadrilaterals will normally be of standard shapes with four sides just like Rectangle, Square, trapezoid, and a Kite or irregular. In the article further, we are going to discuss MCQ on Quadrilaterals. There are a total of 10 MCQ on Quadrilaterals.


Types of Quadrilaterals

There are different types of Quadrilaterals. The word ‘Quad’ means four, and all these types of Quadrilaterals have four sides, the sum of the angles of these shapes is 360 degrees.

  1. Trapezium

  2. Parallelogram

  3. Squares

  4. Rectangle

  5. Rhombus

  6. Kite

  7. A Parallelogram Is a Quadrilateral where the opposite sides are parallel to each other. 

  8. A Rectangle is a Parallelogram where all the angles are equal to 90 degrees.

  9. A Rhombus is a Parallelogram where all four sides are equal.

  10. A Square is a Rectangle where all four sides are equal.

  11. A Trapezium is a Parallelogram where one pair of the opposite side is parallel to each other

  12. A Kite is a Parallelogram where Two pairs of adjacent sides are equal

Other way to Classify the types of Quadrilaterals are given below:

  1. Convex Quadrilaterals: Both diagonals of a Quadrilateral are completely put up within a figure.

  2. Concave Quadrilaterals: At least one of the diagonals is present partly/entirely outside of the figure.

  3. Intersecting Quadrilaterals: Intersecting Quadrilaterals are not simple Quadrilaterals where the pair of non-adjacent sides intersect. These kinds of Quadrilaterals are also known as the self-intersecting or crossed Quadrilaterals.

We will also discuss MCQ on Quadrilaterals in this article.

MCQ on Quadrilaterals Class 9

Solve the questions given below with four multiple options and choose the correct one from them. Given below are MCQ on Quadrilaterals. There are a total of 10 MCQ on Quadrilaterals.

1. The Quadrilateral Having All its Sides as an Equal and Angles Which are Equal to 90 Degrees, it is Called:

a. Rectangle

b. Square

c. Kite

d. Parallelogram

Ans: b

2. The Sum of All of the Angles for a Quadrilateral Equals :

a. 180°

b. 270°

c. 360°

d. 90°


3. A Trapezium Has:

a. One pair of the opposite sides parallel

b. Two pair of the opposite sides which are parallel to each other

c. All of its sides are equal

d. All of the angles are equal

Ans: a

Explanation: A Trapezium has one pair of the opposite sides which are parallel to each other, and the other two sides are non-parallel. 

4. A Rhombus can be a:

a. Parallelogram

b. Trapezium

c. Kite

d. Square

Ans: d


5. A Diagonal of the Parallelogram Divides it Into Two Congruent:

a. Square

b. Parallelogram

c. Triangles

d. Rectangle

Ans: c

6. In a Parallelogram, the Opposite Angles are:

a. Equal

b. Unequal

c. Cannot be determined

d. None of the above


7. The Diagonals of the Parallelogram:

a. Equal

b. Unequal

c. Bisect each other

d. Have no relation


8. Each Angle of the Rectangle is:

a. More than 90°

b. Less than 90°

c. Equal to 90°

d. Equal to 45°


Explanation: ABCD is a Rectangle, and ∠A equals 90°

AD || BC and AB is a transversal

∠ A + ∠ B equals 180° (Interior angles are on the same side of the transversal)

∠ A = 90°

So, ∠ B equals 180° – ∠ A equals 180° – 90° equals 90°

Now, ∠ C = ∠ A and ∠ D = ∠ B (Opposite angles of the Parallelogram)

So, ∠ C equals 90° and ∠ D equals 90°

Hence all sides are equal to 90°.

9. The Angles of the Quadrilateral are in Ratio 4: 5: 10: 11. The Angles are Given Below:

a. 36°, 60°, 108°, 156°

b. 48°, 60°, 120°, 132°

c. 52°, 60°, 122°, 126°

d. 60°, 60°, 120°, 120°

Ans: b

Explanation: x be the common angle between all the four angles of a Quadrilateral.

As per the angle sum property, we know that:

4x+5x+10x+11x = 360°

30x = 360°

x = 12°

Hence, angles are

4x = 4 (12) = 48°

5x = 5 (12) = 60°

10x = 10 (12) = 120°

11x = 11 (12) = 132°


10. If ABCD is a Trapezium in Which AB || CD and AD = BC, then:

a. ∠A = ∠B

b. ∠A > ∠B

c. ∠A < ∠B

d. None of the above


Explanation: Draw a line through C which is parallel to DA and intersecting AB which was produced at E.

CE = AD (Opposite sides)

AD = BC (Given)


⇒ ∠CBE = ∠CEB


∠A + ∠CBE equals 180° (Angles which are on the same side of the transversal and ∠CBE equals ∠CEB)

∠B + ∠CBE equals 180° ( As a Linear pair)

⇒ ∠A = ∠B
