None of these
Explanation
Properties of rectangle are :
$$\Rightarrow$$ Each of the interior angles is 90$$^\circ$$.
$$\Rightarrow$$ Opposite sides of rectangle are parallel.
$$\Rightarrow$$ Opposite sides of rectangle are equal.
$$\Rightarrow$$ So, by joining pair of shapes of option B and C we will not form rectangle because they are not satisfying all the properties of rectangle.
$$\Rightarrow$$ So, only joining pair of shapes of option A, can form a rectangle because it's satisfy all the properties of rectangle.

Explanation
There are four right angles in the figure which are $$ \angle PSR, \angle SRQ , \angle RQP , \angle QPS $$
Given : AB || CD.

Straight
Explanation
$$\angle 1$$ and $$\angle 2$$ are supplementary angles .
$$\Rightarrow \angle 1+\angle 2={ 180 }^{ \circ }$$
Now $$\angle 2$$ is given acute
$$\Rightarrow \angle 2<{ 90 }^{ \circ }$$
$$\Rightarrow \angle 1>{ 90 }^{ \circ }$$
So it is an obtuse angle.
An angle which measures $$\displaystyle 90^{\circ}$$ is called

None of these
Explanation
If all the angles of a triangle measure less than $$\displaystyle { 90 }^{ o }$$, then such a triangle is called acute angled triangle. For eg: An equilateral triangle with all the angles equal to
$$\displaystyle { 60 }^{ o }$$ is acute angled triangle.
An angle which is more than $$180^{\circ}$$ and less than $$360^{\circ}$$ is called:

complete angle
Explanation
By definition, we know, an angle which is more than $$180^o$$
180∘
and less than $$360^o$$
360∘
is called reflex angle.
That is, an a
ngle
larger than a straight
angle
but less than $$1$$ turn (between $$180^o$$ and $$360^o$$) are called
reflex angle.
Therefore, option $$C$$ is correct.

Explanation
From the given options, ball is an example of a sphere.
We know, a sphere is a three dimensional figure, which is made up of all points in the space, which lie at a constant distance called radius, from a fixed point called the centre of the sphere.
Hence, option $$A$$ is correct.

Explanation
Given three lengths of sides are different.
Also, the sides do not follow Pythagora's theorem.
So, it is a scalene triangle.

A triangle can have :
Report Question

one right angle
0%
two right angles
0%
three obtuse angles
0%
none of these
Explanation
Right angled triangle is a type of a triangle where one angle is right angle.
By angle sum property, sum of angles of a triangle $$= 180^{o}$$
If two angles are right angles in a triangle, then according to angle sum property, third angle $$= 0^{o}$$
This is not possible for a triangle.
So, other two angles have to be acute angle.
$$A$$ is the answer.
Measure of an obtuse angle is:

$$> 90^{\circ}, < 180^{\circ}$$
0%
$$> 0^{\circ}, < 270^{\circ}$$
0%
$$> 0^{\circ}, < 180^{\circ}$$
Explanation
Measure of an obtuse angle is always greater than $$0^o$$ and less than $$180^o$$.
Therefore, it can be written as
Obtuse angle is $$>$$ $$90^{\circ}$$ & $$<$$ $$180^{\circ}$$

Explanation
Height, width and depth are the three dimensions of an object or a shape.
An object that has height, width and depth, like any object in the real world are known as three dimensional or 3D shapes.
3D shapes are difficult to be drawn on a flat piece of paper.
Sphere, Cylinder and Cone have all the three dimensions and hence are three dimensional shapes.

Explanation
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.
