<u><em>Answers:</em></u>
Rotating
Reflecting
Translating

<u><em>Explanation:</em></u>
Congruence transformation is a transformation that does not change neither the side lengths nor the measures of the angles.
This means that the formed image is an exact copy of the original figure

<u>Now, let's check the options:</u>
<u>1- Shrinking:</u> This means that we are decreasing the side lengths. 
This option is incorrect

<u>2- Rotating:</u> This means that we are just changing the orientation of the figure without altering any measurements.
This option is correct

<u>3- Reflecting:</u> This means that we are just changing the orientation of the figure without altering any measurements.
This option is correct

<u>4- Stretching:</u> This means that we are increasing the side lengths. 
This option is incorrect

<u>5- Translating:</u> This means that we are just changing the position of the figure without altering any measurements.
This option is correct

Hope this helps :)

Korvikt [17]

Answer:


Step-by-step explanation:

Bill + 220

Total is 538 so subtract 220 which gives you 318.

318/2 = 159

159+220 for Bill = 379

Bob has 159

Add 159 + 220 for Bill and 159 for bob = 538

So Bill has 379

and Bob has 159

madreJ [45]

Answer: x=12

First, you do 8 squared = 4(4+x)

Then, you distribute and becomes a two-step equation.

64=16+4x.

So x=12.

PLEASE HELP!!!!!!!!!!

Answer:

a = 30

b = 15

c = 3

d = 30

e = 10

f = 20

Step-by-step explanation:

60 deg and a + 30 are alt int <S and congruent

a + 30 = 60

a = 30

a + 30 and a + 2b are corresponding angles and congruent

a + 2b = a + 30

2b = 30

b = 15

a + 2b and 5b - 5c are vertical angles and congruent

5b - 5c = a + 2b

5(15) - 5c = 30 + 2(15)

75 - 5c = 30 + 30

75 - 5c = 60

-5c = -15

c = 3

a + 2b and 10c + d are corresponding angles and congruent

10c + d = a + 2b

10(3) + d = 30 + 2(15)

d + 30 = 60

d = 30

5b - 5c and 2d + 6e are supplementary and add to 180

5b - 5c + 2d + 6e = 180

5(15) - 5(3) + 2(30) + 6e = 180

75 - 15 + 60 + 6e = 180

6e + 120 = 180

6e = 60

e = 10

2d + 6e and 4f + 4e are alt int angles and congruent.

4f + 4e = 2d + 6e

4f + 4(10) + 2(30) + 6(10)

4f + 40 = 60 + 60

4f + 40 = 120

4f = 80

f = 20
