Math honework? Easy 10 points

Determine whether the polygons are similar. If so, write a similarity
statement and give the scale factor. If not, explain.
Triangle ABC: 9,9,9
Triangle FED: 15,15,15

Triangle BACD: 4,4,4,4
Triangle EDGF: 6,6,6,6

KJL: 16,30,34
QPR: 8,15,17

PLEASE ANSWER IM DESPERATE AND HAVE A DEADLINE AND IM SO TERRIBLE AT GEOMETRY!!

Triangles ABC and FED are similar. The ratios of the corresponding sides are 9:15, 9:15, and 9:15, which is a 3:5 ratio.

Quadrilaterals BACD and EDGF are similar. The ratios of the corresponding sides are 4:6, 4:6, 4:6, and 4:6, which is a 2:3 ratio.

Triangles KJL and QPR are similar. The ratios of the corresponding sides are 16:8, 30:15, and 34:17, which is a 2:1 ratio.

To determine if the figures are similar, find the ratio of the corresponding sides. If you reduce the ratios and find that they are all the same, the figures are similar, with a side ratio of the ratio you just found. If at least one ratio is different, the figures are not similar. You can explain this by writing the two different ratios of the two different pairs of corresponding sides.

they are all similar.


the first one is 5/3

the second is 3/2

the third is 1/2

Here hope this helps:

Good luck :)

I really can't do math right now, but all are similar. you can think of a statement yourself, soree :(
