Answer: Rotations, reflections, translations (A, C, and E)
Imagine you had a camera aimed at a triangular figure on a piece of paper. If you rotate the camera, then the image of the triangle appears to rotate. In reality it's the other way around. What this means is that the triangle is not changing at all. It keeps the same size, shape, area, perimeter, etc. This applies to when the camera pans left or right, ie shifts from side to side. The triangle will translate but again the triangle isn't changing at all. It's merely an illusion. Reflections are the same way. Imagine having a piece of glass or a mirror that reflects the image which is an identical copy; although everything is flipped.
Dilations are not isometries because the image is a different size then the pre-image. The same shape is maintained though. Note: the scale factor must be some number other than 1.
another note: "isometry" breaks down into "iso+metry" with "iso" meaning "same" or "equal", and "metry" meaning "measure". So if you had 2 identical yard sticks, then they are isometrical or equal in length.

the answer is 3000 pounds.
Step-by-step explanation:
1 ton is 2000 pounds so you just have to multiply 1500×2.

1, 2, 3 and 4 are correct.
5. 75%
6 is also correct
7. 100%
8. 50%
Answer: D.yes, both pairs of opposite sides are congruent.
Step-by-step explanation:
- A parallelogram is a kind of quadrilateral( a- closed polygon having four sides ) with opposite sides parallel and equal.
Its opposite angles are also congruent.
In the given figure , we have a quadrilateral.
Since , the opposite sides of the quadrilateral are shown equal.
Therefore , we can say that the given figure is a parallelogram.
Hence, the correct answer is D.yes, both pairs of opposite sides are congruent.
