Question

1. Sides of triangles are given below. Determine which of them are right tria
In case of a right triangle, write the length of its hypotenuse.
EXERCISE 6.5
(i) 7 cm, 24 cm,
25 cm
(ü) 3 cm, 8 cm, 6 cm
(ii) 50 cm, 80 cm, 100 cm
(iv) 13 cm, 12 cm, 5 cm​

Answer 1

Answer:

Step-by-step explanation:

to check wether the triangle is a right agle triangle here are the steps:

(i)7cm,24cm,25cm

if it is a right angle triangle then the largest number would be the hypotenuse

and the square hypotynuse is equal to the sum of the square of the other two numbers

so the first step would be taking a square of all the numbers

=7^2+24^2=25^2

=49+576=625

so it is a right angle triangle and the hypotenuse is the longest side so the side with 25 as its lenght would be the hypotenuse

(ii)3cm,8cm,6cm

so

3^2+6^2=8^2

9+36=64

9+36 is 45 which is not eqal to 64

so this not a right angle triangle

i hope you can solve the rest
