What is a ray?
a part of a line that has a fixed starting point, but no end point.
100
What is rotation?
move every point of a figure around a center point by a given angle in a specific direction.
100
Draw an image that reflects the quadrilateral below:
Every point should be opposite of itself.
100
using a transformation sequence - how does the blue triangle move to the green triangle?
It first moves to the right
then it moves down
then it rotates about 90 degrees from point B.
100
When you reflect points on the X Axis how are they presented on a plane?
they reflect either left or right from the coordinate point
200
What is a "Degree"?
a unit of measuring angles
200
What is reflection?
a new point across a line that moves every point on a figure to a point directly opposite of the line.
200
Rotate the quadrilateral in the image 100 degrees clockwise around point C.
It should be slightly more than a right angle.
200
What is a transformation sequence?
it is the order in which you move a shape across, down or around a plane.
200
When you reflect from the Y - Axis how are these points represented on the plane?
they are reflected either up or down from the coordinate points.
300
What is a straight angle?
an angle that forms a line and measures 180 degrees.
300
What does it mean to rotate clockwise, or turn clockwise?
turn to the right
300
Extra - What is Ms. McCall's Fiance's name?
Corey
300
what is a transformation?
A translation, rotation, reflection or dilation or a combination of these.
300
When given a coordinate point (9,-5) - which value is on the y axis and which value is on the x axis?
9 is on the x axis
-5 is on the y axis
400
Describe the picture using geometric language.
Reflection
400
What does it mean to turn counter clockwise, or rotate counter clockwise?
turn to the left.
400
What are Ms. McCall's dogs names?
Dilly, Lulu, Archie
400
If you were to describe a rotation of triangle ABC, what information would you need to include in your description?
You would need to know what point is your center point and how much of a degree would be needed for the rotation.
400
Do you reflect points the same way you reflect triangles?
Yes
500
Describe the picture using geometric language.
Rotation
500
What transformation is happening in this image?
Translation - when you move a figure without turning it.
500
Which of the triangles below are a translation of Triangle A? (Remember Translation means moving the triangle without rotating or reflecting it!)
B and D.
500
How many pets does Ms. McCall have total?
4
500
Reflect the following points along the y axis.
A - (6,4)
B - (-3,2)
C - (0,-1)
