Question

Help with SIMILAR POLYGONS?

Answer 1

If 2/3 = x/y, then which of the following must be true?

(2 + x)/3 = (x + 2)/y

3/2 = x/y

(2 + 3)/3 = (x + y)/y

(2 + 1)/3 = (x + 1)/y

Answer 2

(2 + x)/3 = (x + 2)/y
cannot be true because the numerators are the same on both sides and can be cancelled which will leave with 1/3 = 1/y which is not what was given.

3/2 = x/y cannot be true because the left hand side is flipped while the right hand side is not.

(2+3) / 3 = (x + y) / y
2/3 + 3/3 = x/y + y/y
2/3 + 1 = x/y + 1
subtract 1 from both sides
2/3 = x/y which is given. So this is true.

You try the last one.
