To slide a polygon vertically and horizontally on a graph or coordinate plane.
What is translation?
For this transformation, you can add/subtract the coordinates depending on the direction you are moving. [Ex. If J(4,6) its image is J'(2,6) under this this transformation 2 units to the right (horizontal/x-axis)]
What is a translation?
The transformation in Exhibit A
What is 90* rotation counter-clockwise?
Using Exbihit F, the sum of <PLA and <PLB.
What is 180?
All angles in a triagle add up to this number.
What is 180*?
To flip a polygon across an axis or linear expression.
What is a reflection
For this transformation, you can simply choose a vertex and follow the written instructions, doing that for every vertex one-by-one.
What is a translation?
Describe the transformation in Exhibit B.
What is a reflection over the y-axis?
Using Exhibit F, the name of these two angles:
<BLM and <LMC
What is alternate interior angles?
Using Exhibit G, this is measure of the missing angle.
What is 65*?
The corner of a polygon, often used a references for translations and rotations.
What is a vertex (vertices)?
For this transformation, you will need tracing paper.
What is a rotation?
The transformation in Exhibit C?
Using Exhibit F, this is the measure of <LMD.
What is 60*?
All angles on a straight line add up th this number.
What is 180*?
The horizontal plane represented on a coordinate grid.
What is the x-axis?
For this transformation, you can switch the symbol of the opposite coordinate depending on the axis you are going over. [Ex. If J(4,6) its image is J'(4,-6) under this this transformation over the x-axis]
What is a reflection?
The transformation in Exhibit D?
What is a reflection across the y-axis and a rotation 90* clockwise?
Using Exhibit F, this is the measure of <QMD.
What is 120*?
Using exhibit H, this is the measure of <y.
What is 50*?
To be equivalent to in value, size, or representation.
What is congruent?
For this transformation, you can switch the coordinates and signs depending on the direction and degrees in which you are performing the transformation.
Ex. If J(4,6) its image is J'(6,-4) under this transformation x* in a particular direction
What is a rotation?
The coordinates of F in Exhibit E if the polygon was reflected across the y axis and translated 1 unit vertically.
What is F'(1,4)?
Using Exhibit F, this is the measure of <PLA.
What is 120*?
Using Exhibit I, this is the measure of <x.
What is 113*?
