This is Honors Geometry Unit 5 compressed. (i will probably write out the questions for the first few questions in all of these)
UNIT 5 LESSON 1
1. In the diagram In the diagram, triangle A'B'C' is an image of triangle ABC. Which rule describes this translation?
B - ( x, y )= ( x + 5, y + 3)
2. The translation (x, y )A photo shows an arrow icon pointing to the right.(x + 3, y – 7) maps TUVW onto T'U'V'W'. What translation maps T'U'V'W' onto TUVW? (1 point)
D - ( x, y) = .(x – 3, y + 7)
3. Which of the following is true for an isometry?
A - The preimage and the image are congruent.
4. triangleRSV has coordinates R(2, 1), S(3, 2), and V(2, 6). A translation maps points R to R' at (–4, 8). What are the coordinates for S' for this translation? (
C - (–3, 9)
UNIT 5 LESSON 3
1. Name the segment which is congruent to line BC.
C - line MN
2. What image is the translation of the shown triangle given by the translation rule (x,y) = (x-2, y+3)
C - (its higher(more y) and more to the left(less x))
3. The vertices of a rectangle are R(-5,-5), S(-1,-5), T(-5,1). After translation, R' is the point (-11,-11). Find the translation rule and coordinates of U'.
4. Which describes the translation represented by the translation rule (x,y) = (x-7, y-7)
A - 7 unites to the left and7 units down
5. Sarah was sitting in a seat at a baseball game when another ticket holder showed her she was in the wrong seat. The other ticket holder kindly told Sarah she needed to go 5 rows down and3 seats to the right. Which rule describes the translation needed to put Sarah in the correct seat?
D (x,y) = (x +3 ,y-5)
6. What translation rule can be used to describe the result of the composition of (x,y) = (x-9, y-2) and (x,y) = ( x+1 y-2 )
C - (x,y) = (x-8, y-4)
7. The vertices of a triangle are P(_7, _4), Q(-7,-8), and R(3,-3). Name the vertices of the image reflected across the line y=x
C - P' (-4,-7), Q (-8,-7), R (-3 , 3)
8. Find the image of O(-2,-1) after two translations, First across the line y= -5 , and then across the line x=1.
C - 4, -9
The hexagon gikmpr and triangle fjn are regular. the dashed line segments form 30 angles
9. D - OF
10. D - 72 degrees
11. C - Rotation
nvm im unrelaiable on this site ikik
and apparently dishonorable, as well ...
ok...
UNIT 5 LESSON 6
(ok so i might not do all the lessons but I'll just do some)
Quiz
1. How many lines of symmetry does the isosceles trapezoid have?
B - the number 1
2. Which letter has at least one line of symmetry
A - the letter D
3. IF the figure gas rotation symmetry find the angle of rotation about the center that results in an image that matches the original figure
B - 120 degrees
4. Name the type of symmetry for the figure/
B
5. C - reduction 1/2
6. C - 200 millimeters
7. B - rotation
8. D (its labeled up to 8 and -8 on both axis the triangle id TOUCHING the y axis but if they change the order and choices idk how to describe it sry)
9. A - opposite orientation; reflection
10. A - rotation; 180 degees about (1, 4)
BOUNUS
How many lines of symmetry does a regular octagon have?
8 lines of symmetry
UNIT 5 LESSON 6
Practice
Compositions of Reflections Practice
1. D - reflections and glide reflections
2. A - translations
3. B - rotation
4. C - reflection
5. D - (0,0) (origin)
good luck! :D (also when i said i was unreliable i meant that because i didn't include all the assessments not that the answers are incorrect)

Test
Part 2
For problem 1 the new endpoints are -12,4
16,-12
8,12
and
-4,16 in alphabetical order
Positive integers for are enlargements, and this one isn't a fraction.
Multiply all the vertices by 4. In fraction's were you scale down its dividing
This isn't by exact answer but please word this differently.
I can't find problem 2 online but problem 3 is 3/4 but can't find an explanation
