Question

Verify whether a ∆ whose sides are 8mm,15mm and 17mm, a right angled or not?
​

Answer 1

Answer: Yes its a right angle triangle

Step-by-step explanation:

Given length = 15 mm , 17mm , 8mm

choose the largest number from the given  : 17mm

then apply pythagoras theorem to check weather it is right angle triangle  

= (17)^2 = (15)^2 + (8)^2          ( if it is equal then its right angle triangle )

=  289 = 225 + 64

=   289 = 289
