Question 1
1 / -0

Mary owns a quadrilateral shaped barren field, all sides of which are of different lengths. She joined the mid-points of the four sides of the field and planted trees in the area enclosed by the lines. The area in which she planted trees is in the shape of a

A
square

B
trapezium

C
parallelogram

D
rhombus

Solution

The quadrilateral formed as a result of joining the midpoints of a quadrilateral is always a parallelogram.

Hence, the correct answer is option C.
Question 2
1 / -0

The midpoints of a rectangle are joined to form a quadrilateral. The midpoints of the quadrilateral thus formed are again joined. This process is continued for the next 5 times. The quadrilateral formed in the last step is a

A
rhombus

B
rectangle

C
parallelogram

D
square

Solution

When the midpoints of a rectangle are joined, the quadrilateral formed is a rhombus and vice-versa.

The correct answer is A.
Question 3
1 / -0

If the angles of a quadrilateral are in the ratio of 6:8:10:12, then what are the angles?

A
15°, 20°, 25°, 30°

B
30°, 40°, 50°, 60°

C
60°, 80°, 100°, 120°

D
120°, 160°, 200°, 240°

Solution

Since the angles of the quadrilateral are in the ratio 6:8:10:12, the angles are 6x, 8x, 10x and 12x.

∴6x + 8x + 10x + 12x = 360° [Angle sum property of quadrilateral]

⇒ 36x = 360°

⇒ x = 10°

Thus, the required angles are 60°, 80°, 100°, 120°.

The correct answer is C.
