Lesson 2
What is the side length of a square with an area of 81 square units?
81
Translations, Reflections and Rotations are types of ...
Rigid motions
Pg 19 #11... Answer the question and explain your reasoning
No, its not under rigid motion because the side lengths are not the same.
What is the cube root of 64?
4
Is 5/11 Rational or Irrational?
Rational
On page 33, # 2 which line maps the figure onto the image provided?
Line JE
Pg 10.. What type of rigid motion is number 10?
Reflection
Pg 20 #12. Answer and explain your reasoning.
No, its not under rigid motion because the side lengths are not the same.
What is the square root of 9?
3
Solve 2x2 * 3x3
6x5
Always, sometimes or never...A translation changes the length of a segment.
Never
Pg 10.. What type of rigid motion is number 11?
Translation
Pg. 20 #14. Answer and explain your reasoning.
No, the angles are the same measurements but the side lengths are not. It needs to meet both criteria to be under rigid motion.
What is the cube root of 125?
5
(5)0=?
1
Always, sometimes or never... A translation maps a line to a parallel line.
Sometimes
Pg 11.. What type of rigid motion is number 12?
Rotation
Pg 21. Part C. Explain
PQRS is also parallel because its a reflection.
What is the cube root of -64
-4
What 0.0007 in scientific notation
7 x 10 -4
A translation maps a line to a line
Always
Pg 11.. What type of rigid motion is number 13?
Translation
Pg 21, Part D. Explain
Yes, because it has at least one set of parallel lines.
