Question

)) A triangle has sides with lengths of 5 inches, 12 inches, and 13 inches. Is it a right

triangle?
yes
no​

Answer 1

Answer:Yes

Explanation:

Given

Triangle has sides

length
`a=5\ in.`

`b=12\ in.`

`c=13\ in.`

If the triangle is Right angled then it must satisfy the Pythagoras rule

`(\text{Perpendicular})^2+(\text{base})^2=(\text{Hypotenuse})^2`

`(a)^2+(b)^2=(c)^2`

`5^2+12^2=13^2`

`25+144=13^2`

`169=13^2`

`13^2=13^2`

Therefore The given triangle is right angled
