Question

The length of the sides of triangle are given of them is a right angled triangle 1 of right angled determine the hypotences .
1. 10cm, 15cm,13cm
2. 80cm

Answer 1

Answer:

Since, (25)

2

=(7)

2

+(24)

2

⇒625=49+576⇒625=625

Hence, 7cm, 24cm and 25cm are the sides of Right Angled Triangle and its Hypotenuse is 25cm

(ii)

Since, (8)

2

=(3)

2

+(6)

2

⇒64

=45

Hence, 8cm, 6cm and 3cm do not form Right Angled Triangle.

(iii)

Since, (100)

2

=(50)

2

+(80)

2

⇒10000



=8900

Hence, 100cm, 50cm and 80cm do not form Right Angled Triangle.

(iv)

Since, (13)

2

=(12)

2

+(5)

2

⇒169=144+25⇒169=169

Hence, 13cm, 12cm and 5cm are the sides of Right Angled Triangle and its Hypotenuse is 13cm.
