In the lesson, you used the following matrices to create reflections:

Across x-axis: A =
[1 0]
[0 −1]

Across y-axis: B =
[-1 0]
[0 1]

Across line y = x: C =
[0 1]
[1 0]

Across line y = −x: D =
[0 -1]
[-1 0]

All these reflections resulted in figures.

All these reflections resulted in   figures.

Congruent

Find the determinant of each of these:

The determinant of each of these is ___.

-1

Now find the following:

A=1  B= 0 C=0 D=1

Repeat this process for the other three matrices. The product of a reflection matrix and its transpose is the  .

Identity Matrix

I took the quiz on edge.

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
