Question

Q3. Classify the following triangle on the bases of sides P 6 cm 5 cm 4 cm 4 cm 4.5 cm с B R 7 cm (i) (ii) M 3 cm 3 cm L N 3 cm (iii)​

Answer 1

Solve:-

We know that, the sum of any two sides of a triangle must be greater than the third side.

Part (1).

2cm,3cm,5cm

Then 2+3=5

So, it is not possible to have a triangle. Because sum of two sides is equal to the third side.

Hence, this is the answer.

Part(2).

3cm,6cm,7cm

Then 3+6=9>7

So, it is possible to have a triangle. Because of sum of two sides are greater than to the third side.

Hence, this is the answer.

Part(3).

6cm,3cm,2cm

Then 2+3=5<6

So, it is not possible to have a triangle. Because of sum of two sides are less than to the third side.

Hence, this is the answer

Answer 2

the answer can be

Step-by-step explanation:

(a) scalene triangle - which does have any side equal

(b) isosceles triangle - which two side are equal

(c) equilateral triangle - which all aide are equal
