Question

name the type of triangle formed by joining a(-5 6) b(-4 -2) and c(7 5)​

Answer 1

Answer:

hope its correct and helps u..

Answer 2

Answer:

$ab = \sqrt{ {( - 5 + 4}^{2} + {(6 + 2)}^{2} } = \sqrt{1 + 64} = \sqrt{65} \\ bc = \sqrt{ {(7 + 4)}^{2} + {(5 + 2)}^{2} } = \sqrt{121 + 49} = \sqrt{170} \\ ca = \sqrt{ {(7 + 5)}^{2} + {(5 - 6)}^{2} } = \sqrt{144 + 1} = \sqrt{145}$

so its an scalene triangle
