Question

sides of traingles are given as 13cm 12 CM and 5 CM determine they form rightangled triangle Or not
​

Answer 1

Answer:

AC^2 =AB^2+BC^2

13 ^2 = 12^2 + 5^2

199 = 144 + 25

199 = 175

so, it is not a right angled triangle

Answer 2

Step-by-step explanation:

by Pythagoras theorem,

largest side is hypotenuse thus

( hypotenuse)²= (perpendicular)2+(base)2

(13)² = (12)²+(5)²

169= 144+ 25

169 = 169

hence ABC is right angle triangle as it fullfills the Pythagoras theorem
