Answer:
(b) Congruent Figures
Step-by-step explanation:
Reflections, rotations, and translations are called "rigid transformations" because they do not change the size or shape of the figure. The image is always congruent to the original.
On the other hand, dilations change the size of the figure, so the image is <em>not congruent</em> with the original.
Rigid transformations result in congruent figures.
The value is 20,000 because 2x10 equals 20, 20x1,000 equals 20,000
You can reduce the first one by combining the ab and the ba term
X=60° (equilateral triangle)
y=120°
Working: (360°-120°)/2
