Triangle J′K′L′ shown on the grid below is a dilation of triangle JKL using the origin as the center of dilation: Two triangles are drawn on a grid. First triangle has vertices J 6 and 12, K 9 and 6, L 12 and 9. Image triangle has vertices J prime 2 and 4, K prime 3 and 2, L prime 4 and 3. Which scale factor was used to create triangle J′K′L′? 1 by 3 4 3 one quarter

Scale factor of 1/3.

Step-by-step explanation:

We can look at the side lengths of each triangle to find the scale factor in which J' K' L' was made through.

KL is 3 units long.

JL is 6 units long.

JK is 6 units long.

K' L' is 1 unit long.

J'L' is 2 units long.

J'K' is 2 units long.

We find here that the side lengths were divided by 3 to get J'K'L, aka, multiplied by 1/3.

Hope this helped!

b or 2, just plug these equations into your graphing calculator then check the graph to see the image. if it matches up then that's your answer!

use formula for the circle a=3.14
