Answer: A. preserves length, angle measures and distance between points
Rigid motions or isometries are any of the three transformations below
- translation (aka shifting)
- rotation
- reflection
Any of those three transformations will keep the figure the same size and shape. That means distances between any two points are kept the same, and angle measures are kept the same as well. Everything is kept the same. The only difference is that the figure is in a different location, is rotated somehow, or it is reflected some way. You can use a series of transformations to undo everything to get the original figure back.
If you wanted to change the size of the figure, then you would apply dilation, which isn't an isometry.

Step-by-step explanation:
Answer:
A. You can replace ‘a number’ with a variable to represent an unknown value.
C. Product means the result of multiplying two numbers.
D. The coefficient is 15.
E. In algebraic notation, you can represent the product of a number and a variable by writing the number and variable next to each other.
Step-by-step explanation:
EDGE 2020
Because she cut off a total of 4 inches, the plank is now 133 inches long. Divide 133 by 7 to get her 7 equal parts, and <u>each shelf will be 19 inches.</u>
