Similar polygons are made through scaling either by stretching or squeezing the sides all by a common ratio. Here, the size changes. Congruent polygons are made by shifting or reflecting their position. Here, the size does not change.
Choice A has a dilution (or squeezing) and a translation (shifting). That makes similar polygons.
Choice B has a rotation. Nope.
Choice C has a shifting and a reflection. Nope.
Choice D has a rotation and shifting. Nope.
Thus choice A is best.
Answer:
Mean: 11.5 Median: 6

Answer:
a) 42.8 degrees.
Step-by-step explanation:
sin-|(-0.27 +0.95) means the angle whose sine is (-0.27+0.95)
= sin-1(0.68)
Using a calculator the answer is 42.8 degrees.
According to my knowledge, kangaroo travelers 1.3 kilometers in 2 minutes
0.4375.
You can simply divide 7 by 16 using long division or a calculator to get this answer.
