7 Questions

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

Q has 2 acute angles and 3 obtuse angles.

If the scale factor between P and Q is \frac{1}{5} then each side length of P is multiplied by \frac{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.

The angle measures are all whole numbers.

The side lengths are all whole numbers.

Q has exactly 1 right angle.

Here is Quadrilateral ABCDPQRS.
Quadrilateral PQRS is a scaled copy of Quadrilateral ABCD. Point P corresponds to A, Q to B,  to R, and S to D.

If the distance from P to R is 3 units, what is the distance from Q to S? Explain your reasoning.
