Question

(a) Show that the triangle ABC is a right triangle by using the converse of the Pythagorean Theorem.
d(A, B) =
d(B, C) =
d(A, C) =

Answer 1

(b) Find the area of triangle ABC.

Answer 2

omg. you have to use the distance formula to find the length of the sides first. omg.

Answer 3

lengthy process my friend.

Answer 4

tis the distance formuler.

Answer 5

what did u find for the distance of the sides? I wanna check my answers

Answer 6

sigh. lemme do em real quick

Answer 7

a-b =3.64

Answer 8

you mean AB?

Answer 9

yes

Answer 10

BC= 6.18

Answer 11

and CA is 3.64

Answer 12

i got different lengths :/

Answer 13

what did u get

Answer 14

AB = 3.2, BC = 6.3, and AC = 7

Answer 15

oh my bad i made an error and said for b that it was (8,3.5) should be (8,4)

Answer 16

okay so what is the answer to this problem

Answer 17

well, you have to see if 3.2^2 + 6.3^2 really does equal 7^2

Answer 18

~49.93

Answer 19

since the Pythagorean theorem is a^2 + b^2 = c^2

Answer 20

49.93 doesnt equal 49

Answer 21

well, we did round :/ so i'm not sure

Answer 22

so what is d(A, B)

Answer 23

please express the answers without rounding

Answer 24

ummm ok.

Answer 25

thanks

Answer 26

ab = 3.16227766017
bc = 6.32455532034
ac = 7.07106781187

Answer 27

i would say that yes. it is a right angle
