Rotations Quiz

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

(from here and below i wont write the questions)

10. D - 72 degrees

11. C - Rotation

there were only 2 but whatever, i also wont give any notes so yeah...
