Question

A triangle has sides with lengths of 15 meters, 47 meters, and 48 meters. Is it a right

triangle?
yes
no

Answer 1

no
the inequality triangle theorem states two sides of a triangle added must be smaller than the biggest side, 15 + 47 > 48

u could also disprove this using the pythagorean theorem
15^2 + 47^2 ≠ 48^2
225 + 2209 ≠ 2304
