Answer:
Step-by-step explanation:
Join OB.
∠A=∠A (common)
![\frac{AP}{AO} =\frac{\frac{1}{2} AO}{AO} =\frac{1}{2} \\\frac{AQ}{AB} =\frac{\frac{1}{2} AB}{AB} =\frac{1}{2} \\\frac{AP}{AO} =\frac{AQ}{AB}](https://tex.z-dn.net/?f=%5Cfrac%7BAP%7D%7BAO%7D%20%3D%5Cfrac%7B%5Cfrac%7B1%7D%7B2%7D%20AO%7D%7BAO%7D%20%3D%5Cfrac%7B1%7D%7B2%7D%20%5C%5C%5Cfrac%7BAQ%7D%7BAB%7D%20%3D%5Cfrac%7B%5Cfrac%7B1%7D%7B2%7D%20AB%7D%7BAB%7D%20%3D%5Cfrac%7B1%7D%7B2%7D%20%5C%5C%5Cfrac%7BAP%7D%7BAO%7D%20%3D%5Cfrac%7BAQ%7D%7BAB%7D)
∴ ΔAPO and ΔAOB are similar.
![\frac{PQ}{OB} =\frac{1}{2} \\](https://tex.z-dn.net/?f=%5Cfrac%7BPQ%7D%7BOB%7D%20%3D%5Cfrac%7B1%7D%7B2%7D%20%5C%5C)
∠P=∠O
∠Q=∠B
So PQ║OB
Similarly RS║OB
∴PQ║RS

Answer:
Option h: 16h
Step-by-step explanation:
To get the answer to the question divide 480 by 30 to get the rate which is 16. So the answer would be H
RS points east; R'S' points north, so there has been a rotation 90° CCW.
After that rotation, point S would be at (1, -1). It is actually at (1, 1), so has been shifted 2 units upward.
A sequence that does the desired mapping is
- c. rotation of 90° CCW about the origin
- b. translation 2 units up
