In similar figures, angles or sides are proportional, but in congruence, figures are exactly the same- angles, sides, and everything. Additionally, similar figures always have the same shape, but not always the same size. But in congruence, figures always have the same shape AND size.
So, corresponding sides for similar figures should be proportional (that is, have the same scale factor. And corresponding sides in congruent figures must be exactly the same.
polygons is a plane figure that is described by a finite number of straight line segments connected to form a closed polygonal chain or polygonal circuit
I believe the answer is C - 60 inches. 60 x 2 = 120, which is both lengths, and since he width is half the length, then 30 x 2 = 60. So 130 (length) + 60 (width) = 180. So 60 inches would be the maximum length for both sides.
