Question

Given a scale factor of 1/2, fine the coordinates for the dilation of the triangle with vertices at (0,0),(0,2) and(4,0)

Can you guys explain this to me?

Answer 1

Sure!

Answer 2

First you have to multiply the first coordinate pair by the scale factor.

Answer 3

ex. (1,3) x scale factor 2 is (2,6)

Answer 4

Do you understand?

Answer 5

if it were (3,-3) dilated with scale factor 3 the new coordinates would be (3x3, -3x3) which would become (9,-9)

Answer 6

Oh i understand :D

Answer 7

is it different with triangles?

Answer 8

Same points

Answer 9

same thing

Answer 10

for (0,0) with scale factor 2 its still (0,0). For your (4,0) with scale factor 1/2 it would become (2,0)

Answer 11

Thank you so much!!
