Question

a triangle has sides of lengths 15.23 and 28. is it a right triangle? explain

Answer 1

assuming that we know what a pythag thrm is?

square them all, add the shotrs together, and compare it to the long

Answer 2

add the *shorts together

Answer 3

why is it a right triangle

Answer 4

if you are asking about the proof of the pythag thrm, thats a bit geometric

Answer 5

if a triangle has short legs: a and b, and a long leg, c

it is a right triangle if and only if: a^2 + b^2 = c^2

Answer 6

i know its a right triangle but i have to explain it to

Answer 7

if you are in elementary math classes, then refereing this to the pythag thrm as i did will suffice

Answer 8

otherwise, you might need to determine the law of cosines, and show that when C = 90, it simplifies to the pythag thrm
