A rotation is a transformation that preserves figure shape, figure sizes, angles and lengths.

Therefore,

  • option A is false, because rotation preserves sizes;
  • option B is false, because rotation doesn't change the figure size;
  • option C is true, because rotation preserves figure angles;
  • option D is true, because rotation preserves lenghts of segments.

Answer: option C and D.

How do u solve two points using the distance formula?
aliya0001 [1]

Step-by-step explanation:

For two points (x₁, y₁) and (x₂, y₂), the distance between them is:

d² = (x₁ − x₂)² + (y₁ − y₂)²

The order of points 1 and 2 don't matter.  You can switch it:

d² = (x₂ − x₁)² + (y₂ − y₁)²

This is basically the Pythagorean theorem for a coordinate system.

Let's do an example.  If you have points (1, 2) and (4, 6), then the distance between them is:

d² = (4 − 1)² + (6 − 2)²

d² = 3² + 4²

d² = 9 + 16

d² = 25

d = 5

If you have points with negative coordinates, remember that subtracting a negative is the same as adding a positive.

For example, the distance between (-1, -2) and (4, 10) is:

d² = (4 − (-1))² + (10 − (-2))²

d² = (4 + 1)² + (10 + 2)²

d² = 5² + 12²

d² = 25 + 144

d² = 169

d = 13
