Question

1. Find the other two sides of the right angled triangle whose smallest side is 12 cm? plss

Answer 1

DATA
length of the smallest side= 12cm

TO FIND
other sides of the triangle

By Pythagoras theorem,
a^2+b^2=c^2
12^2 = c^2-b^2

By trial and error method, we get,
12^2 = 20^2-16^2
144 = 400-256
144 = 144

Hence the length of the other sides are 16cm and 20cm.

Hope this is helpful.

Answer 2

Given :   right angled triangle whose smallest side is 12 cm

To Find :   other two sides of the right angled triangle

Solution:

A Pythagorean triplet  2m , m² - 1  & m² + 1

smallest side is 12 cm

=> 2m = 12

=> m  =  6

m² - 1  = 6² - 1  = 35  cm  

m² + 1  = 6² + 1  = 37  cm  

Pythagorean triplet is :

12 , 35 , 37

other two sides of  right angled triangle   are  35 cm & 37 cm

if we take m = 6/2   = 3

then Each side  will be  2(2m)  ,  2( m² - 1)  & 2 (m²+ 1)

12  ,  16   & 20  cm

Here other two sides are  16 & 20 cm  

in this way we can got lot of combination of other sides
