Question

Does the following lengths form a right triangle?
a) 5 dm, 12 dm, 13 dm​

Answer 1

Answer:

yes see 13 dm is hypotenuse as it is big than other nos

h(2) =b(2) + p(2)

13(2)=12(2)+5(2)

169=144+25

169=169

so it is a right triangle as it has p(2) as 90degree

Step-by-step explanation:

12 DM is perpendicular or height and 5 dm is base

Answer 2

$\huge\sf\underline\red{Concept}$

According to pythagoras theoram In a right angle triangle square of hypotenuse is equal to sum of square of other two sides

a²+b²=c²

_______________________________________________

$\huge\sf\underline{Solution}$

So,

a²+b²=c²

5²+12²=13²

25+144=169

169=169

Hence the given sides form a right angle triangle
