Question

Show algebraically that the vertices A (13,3) B (13,5) and C (=2.20) form a right angle triangle.

Answer 1

1st off , you need to calculate , [AB] , [AC], [BC]
we don't where the menu corner is , do you have anyidea what to do next ?

Answer 2

is this to help find the slope of the triangle?

Answer 3

nope not at all

Answer 4

what do you mean by that because I'm already calculating the slope.

Answer 5

we know that , AB² + AC² = BC² if BC is the longest , so A is going to be our square

Answer 6

ohhhh so I figuerd out the slope for AB and AC now I need figure out BC

Answer 7

AB's slope is \[\frac{ 2 }{ 16 }\]

Answer 8

AC's slope is \[\frac{ -23 }{ -15 }\]

Answer 9

how did you find those ?
