I think the correct answer would be C. A validation of congruency between two polygons would be that if by applying rigid motions you can make them coincide. Two figures are said to be congruent if and only if these figures have the same shape and the same size. All of their sides and angles are the same. Rigid motion is a motion done to a figure that preserves distance or length. If all the rigid motions like rotation, reflection, translation and glide reflection are done and the figures are the same or the lengths are preserved, then the polygons should be congruent.
Answer:
6/5 1.2 1 1/5
Step-by-step explanation:
1+2+3=6
You do not change the denominator while adding fraction so it remains the same at 5

the formula for area of a circle: pi * r^2
find the area of the larger circle using the radius of 18m, then subtract the area of the smaller circle using a radius of 13m
Step-by-step explanation:
the answer is C. :)))))
