Question

The sides of a triangle are 7 cm ,24 cm and 25 cm . Is this triangle a right angled triangle?​

Answer 1

Answer:

i

Step-by-step explanation:

if it is a right angle triangle it must follow hypotenuse rule

so a^2+b^2=c^2

assuming the highest side is hypotenuse we can can calculate the result using above formula

${7}^{2} + {24}^{2} = {25}^{2}$

49+576=625

625=625

hence it is a right angled triangle

Answer 2

Sides of a triangle = 7 cm , 24 cm, 25 cm .

According to Pythagoras theorem , the sum of the square of the two smallest side [Base & Perpendicular ] must be equal to the square of the longest side [ Hypotenuse ]. If a triangle has this property it is a right angled triangle .

Now , according to the formula ,

(H)² = (B)² + (P)²

=> (25)² = (24)² + (7)²

=> 625 = 576 + 49

=> 625 = 625 .

So , as they are equal . The triangle is a right angled triangle .
