Answer:

see attached

Step-by-step explanation:

When the sequence of sides (shortest to longest, for example) remains the same (CW or CCW), then the number of reflections is even, possibly zero. The figure will have been translated if all of the corresponding sides retain their original direction, otherwise rotation is involved.

If the sequence is reversed, as in the upper right and lower left figures, then reflection is involved. The line of reflection will be the line through the midpoints of the segments connecting corresponding vertices.

Angle Sum Theorem. y = ?

salantis [7]

Answer:

90°

Step-by-step explanation:

Interior angles of ALL triangles sum to 180°

The whole large triangle has angles 60 60 60 ( they sum to 180)

that means x = 30

then the small triangle on the right has 60 + 30 + y = 180

meaning y = 90 °

Explain how to factor when the leading coefficient is 1.

Bas_tet [7]

Answer: C) Find the factors of c that add up to b.

==============================================

Explanation:

If we want to factor something in the form x^2+bx+c, then we look for two numbers that

Multiply to c
Add to b

-------------

Let's look at a specific example

Consider factoring x^2+5x+6

We need to find two numbers that...

Multiply to c = 6
Add to b = 5

Through trial and error, you should find the two numbers to be 3 and 2. This means it factors to (x+3)(x+2). The order of the factors doesn't matter.

You can use the FOIL rule or the box method to expand out (x+3)(x+2). You should get x^2+5x+6 again.
