Question

The Coodinates Of ABC Triangle Are A(-4,2),B(5,0),C(4,4). Calculate The Lengths Of AB,BC and AC​

Answer 1

Step-by-step explanation:

AB length =root85

BC length =root 17

AC length =root 68

Answer 2

Answer:

If A (x1, x2), B (x2, y2) and C (x3, y3) are the coordinates of vertices of triangle ABC

THEN

AB = Square root [ (x2-x1)^2+(y2-y1)^2

Similarly BC = Square root [ (x3-x2)^2+(y3-y2)^2

and   CA = Square root [ (x1-x3)^2+(y1-y3)^2

here A(-4,2),B(5,0),C(4,4)

so ⇒AB = Sqrt [ {5-(--4)}^2+(0-2)^2

⇒ AB = $\sqrt{85}$

Similarly we can find others
