What is the sum of the measures of the exterior angles of a polygon?
360 degrees
100
What is a transformation?
A change madeto the size or the location of a figure.
100
What is a reflection?
A transformation in which a figure is flipped in a line
200
What are supplementary angles?
Two angles that equal 180 degrees
200
What are the types of angles formed when a transversal intersects two lines?
Correspoding angles, alternate interior angls, and alternate exterior angles
200
What is the formula to find the measure of an interior angle of a polygon?
(n-2)*180 ----------- n
200
What is an image and what things are used to identify the image in the book?
An image is the result of a transformation;the color red and prime notation
200
How do you know if a figure has line symmetry?
If a line divides the figure in two parts that are reflections of each other in the line
300
Give an example of complementary and supplementary angles.
Answers may vary. Sample answer:30 degrees and 60 degrees; 90 derees and 90 degrees
300
What kind of lines does a transversal have to intersect so certain pairs of angles have equal measures?
Parallel lines
300
What is the measure of an interior angle in a regular pentagon?
108 degrees
300
What is a translation?
A translation is a transformation in which each point of a figure moves the same distance and in the same direction
300
How can you use coordinate notation to find the coordinates of a figure after a reflection in the x-axis?
Multiply the y-coordinate by -1
400
What are adjacent angles?
Angles that have a common ray and they share the same vertex.
400
Fill in the blank: If a transversal intersects two lines so that the corresponding angles have the same measure, then the les are ________.
Parallel
400
What is the sum of an exterior angle in a regular hexagon?
60 degrees
400
What is coordinate notation?
A way to describe a translation of each point(x,y) of a figure
400
How can you use coordinate notation to find the coordinates of a figure after a reflection in the y-axis?
Multiply the x-coordinte by -1
500
What are vertical angle? Tell about the similarities between angles.
When two lines that intersect at one point, the angles opposite of each other are vertical angles. Vertical angles have the same measure.
500
Where would corresponding angle be located on the tranversal?
To the right or to the left of the transversal.

What is the sum of the interior angles of a regular heptagon?
900 degrees
500
What is a tessellation?
A repeating pattern of one or more shapes with no gaps or spaces.
