Question

2.The sides of certain triangles are given below. Determine which of them are right
triangles?
(i) a =6cm, b = 8 cm and c = 10 cm
(ii) a = 5 cm, b= 8 cm and c = 11 cm​

Answer 1

Answer:

we can use pythorous therom for this.

6^2+8^2=36+64=100=10^2

so it's a right angle triangle

5^2+8^2=25+64=!11^2

so it's not right angle triangle

Answer 2

Answer:

(i)

Step-by-step explanation:

Hypnoteuse ^2=Base^2+Height^2

(i)

A^2+B^2=C^2

Or,6^2+8^2=10^2

Or,36+64=100

Or,100=100

LHS=RHS. So, (i) is a right angled triangle.

(ii)

A^2+B^2=C^2

Or,5^2+8^2=11^2

Or,25+64=121

Or,89≠121

LHS≠RHS. So, (ii) is not a right angled triangle.
