Question

A triangle has sides with lengths of 26 yards, 76 yards, and 78 yards. Is it a right triangle?

Options:
Yes
No

Answer 1

No it’s not :)




I hope this helps

Answer 2

No

Explanation:

a^2 + b^2 = c^2

Since 78 is the largest it will be c.

26^2 + 76^2 = 78^2

676 + 5776 = 6084

6452 does NOT = 6084

Since c^2 is larger it is an obtuse triangle.
