Question

4. What kind of triangle is made by connecting the points A(0, –6), B(3, –6), and C(3, –2)?
Is it right
Isoceles
or right and isoceles

Answer 1

how bout we drop it to the origin? thatll cancel out one of the points then

Answer 2

how do we do that?

Answer 3

well, to move a set of points, you add the same value to all of them

Answer 4

notice the point 0,-6 ; what point value would you add to this to get 0,0?

Answer 5

lets try that again ....

(0,-6)
+ ( ? , ? )
---------
(0,0)

Answer 6

0,6

Answer 7

good, so that tells us that if we add 6 to all the y parts ... this will put a vertex at the origin and cancel it out of the process

what is our new set of points (0,0) ..... ?

Answer 8

(0,0) (3,0) (3,4)??

Answer 9

A(0, –6), B(3, –6), and C(3, –2)
6 6 6
--------------------------
A (0, 0), B(3, 0), and C(3, 4)

i like it :)

Answer 10

now, if this was a right triangle, all our points would have a 0 in them ... do you see why?

Answer 11

i think so, so does this mean it is isoceles?

Answer 12

err, srry i envisioned the wrong shape ... lets draw this :)

Answer 13

okay
