Question 1
1 / -0

Which of the following statements is sufficient to construct a triangle of proper measurement?

A
One side length and one angle

B
Two angles

C
Only one side

D
Two angles and one side length

Solution

A triangle can be drawn if any one of the following sets of measurements are given:

(i) Three sides

(ii) Two sides and the angle between them

(iii) Two angles and the side between them

(iv) The hypotenuse and a leg in the case of a right triangle

Thus, two angles and one side length is sufficient to construct a triangle of proper measurement.
Question 2
1 / -0

What is the product of number of vertices and sum of number of sides and angles of a triangle?

A
9

B
18

C
22

D
36

Solution

It is known that the number of vertices, sides, and angles of a triangle is 3 each.

∴ Required product = 3 × (3 + 3) = 3 × 6 = 18

Thus, the product of number of vertices and sum of number of sides and angles of a triangle is 18.
Question 3
1 / -0

If one of the angles in a two-dimensional figure of three sides is 90° and the lines forming that angle are equal in length, then the figure is an

A
acute triangle

B
equilateral triangle

C
isosceles right triangle

D
acute isosceles triangle

Solution

An isosceles right triangle is a two dimensional closed figure. One of its angles is 90° and the lines forming that angle are equal.
