What's the answer? Lots of points! :)

These two figures are congruent because I used the transformation (rotation) and using the distance formula to solve my work.

Step-by-step explanation:

This is what I said on my test and I got 10 but that's beacuse my teacher knew what I was doing

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
