1 / -0

The number of corner in a cone is

A
$$1$$

B
$$2$$

C
$$3$$

D
None of these

Solution

A cone has $$1$$ corner.
Question 2
1 / -0

The number of corners in a cube are

A
$$4$$

B
$$6$$

C
$$8$$

D
$$12$$

Solution

A cube has $$8$$ corners.
Question 3
1 / -0

Which of the following is/are two dimensional figures?

A
Square

B
Circle

C
Cube

D
Both A and B

Solution

Any shape that can be laid flat on a piece of paper or any mathematical plane is a 2D figure. Two dimensional or 2D figures can be summarized by calling them flat shapes.
Width, height and thickness are the dimensions of an object.
A shape that has only two dimensions that is width and height are also know as two dimensional objects or figures.
Two dimensional objects do not have thickness.
Hence, square and circle are 2D figures since they lay flat on the paper and do not have thickness.
Cubes have thickness and hence they are not two dimensional figures.
Question 4
1 / -0

The flat surface of a solid figure is called a

A
Vertex

B
face

C
edge

D
None of these

Solution

The flat surface of a solid figure is called a face
Question 5
1 / -0

A geometrical shape with no vertices and no flat surfaces is

A
Sphere

B
Cone

C
Cylinder

D
None ofthese

Solution

A geometrical shape with no vertices and no flat surfaces is $$sphere.$$
As sphere is spherical in shape.
Question 6
1 / -0

The faces of a cube are

A
Squares

B
Rectangles

C
Circles

D
None of these

Solution

The faces of a cube are square
Question 7
1 / -0

How many edges a cuboid has?

A
6

B
8

C
12

D
16

Solution

Cuboid has 12 edges
Question 8
1 / -0

$$\displaystyle 96^{0}$$ is an example of-

A
Acute

B
Obtuse

C
Right

D
None of these

Solution

obtuse angles are those angles which are greater than 90 degrees and less than 180 degrees..
so,96 degrees is an example of obtuse angle..
Question 9
1 / -0

A Rhombus also satisfies the properties of a:

A
Square

B
Parallelogram

C
Trapezium

D
None of these

Solution

A rhombus is a parallelogram. The definition of a parallelogram is a quadrilateral that has $$2$$ pairs of parallel lines.

A parallelogram has properties including $$2$$ pairs of congruent sides, $$2$$ pairs of congruent opposite angles, supplementary consecutive angles, and diagonals that bisect each other.

A rhombus has all of these properties.
Question 10
1 / -0

The triangle formed by $$BC=8.2 cm$$, $$AC=7 cm$$ and $$ \displaystyle \angle C = 120^{\circ} $$ is-

A
An obtuse angled triangle

B
An acute angle triangle

C
A right angled triangle

D
None of these

Solution

In△ABC,
$$BC=8.2cm,AC=7cm$$ and $$\angle C=120°$$

Here, we can see triangle contain one obtuse angle.

So,△ABC, is an obtuse angled triangle
Option A is the correct answer.
