Scale Drawings HW 4-9

Select all the statements that must be true for any scaled copy Q of Polygon P.

• The side lengths are all whole numbers.

• Q has 2 acute angles and 3 obtuse angles.

• Q has exactly 1 right angle.

• If the scale factor between P and Q is 1/5, then each side length of P is multiplied by 1/5 to get the corresponding side length of Q.

• If the scale factor is 2, each angle in P is multiplied by 2 to get the corresponding angle in Q.
