Question

prove that (3, 0) (6, 4) (-1, 3) are vertices of isoselous triangle​

Answer 1

Here is ur answer

Let A(3, 0), B (6, 4) and C(-1, 3) be the given points

(AFTER THE IMAGE)

⇒ AC=√ (16+9)

⇒ AC=√(25)

⇒ AB2=(√25)2

⇒ AB2=25

⇒ AC2=25

⇒ BC2=(√50)2

⇒ BC2=50

Since AB2+AC2=BC2 and AB=AC

∴ ABC is a right angled isosceles triangle

Hope it helps :)
