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

Step-by-step 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
