Question

the first to answer will be marked the brainliest ​

Answer 1

Answer:

Slope of AC = ( 6 - -2 ) / ( 10 - 4 ) = 8 / 6

Slope of AB = ( 4 - -2 ) / ( -4 - 4 ) = 6 / -8

( slope of AC ) × ( slope of AB ) = ( 8/6 ) × ( 6/-8 ) = -1

Therefore AC and AB are perpendicular

Answer 2

hi mate

1)The first thing I'd that take

AB

BC

AB

2)Now find the distance between

AB

and

BC

AND

CA by the formula

$\sqrt{(x2 - x1) { }^{2} } + \sqrt{} (y2 - y1) {}^{2}$

x2 minus x1 whole Square plus y2 minus y1 whole square

hope this may help you
