Question

Isosceles triangle XYZ is placed on a coordinate plane to be used for a coordinate proof. What should the coordinates of its vertices be?

Answer 1

on this one?

Answer 2

is this the only information you have?

Answer 3

yes it has a multiple choice to it

Answer 4

type in the multiple choice.

Answer 5

All of the following are suitable for a general isosceles triangle.

i. (-a,0), (0,b), (a,0)
ii. (b,b), (0,-a), (-a,0)
iii. (-b,-b), (0,a), (a,0)
iv. (-b,b), (0,-a), (a,0)

Otherwise type in your multiple choice if non of these are on there.

Answer 6

A. (-a,0), (0,0), (a,0) B. (0,0), (0,-a), (-a,0) C (0,0), (0,a), (a,0) D. (0,0) (0,-a), (a,0)

Answer 7

Although not my area of expertise, I would go with c)

a) is clearly out as it represents a straight line. b), c) and d) are all valid points for an Isosceles triangle. However, only c is in the postive quadrant. Corodinate proofs in the negative quadrants are, apparently, confusing and cumbersome.

Answer 8

thank you so much

Answer 9
