What is their corresponding angles?
100
A flip is another name for this transformation.
What is a reflection?
200
This pair of angles adds to 180 degrees.
What are supplementary angles?
200
This is a quadrilateral with only one pair of parallel sides.
What is a trapezoid?
200
This is any polygon with all sides congruent and all angles congruent.
What is a regular polygon?
200
If a similar figure is the same size as well as the same shape, then it is called this.
What is congruent?
200
A slide is another name for this transformation.
What is translation?
300
These angles are found in the same relative location -- either when lines are intersected by another line or when looking at two similar figures.
What are corresponding angles?
300
This type of triangle has no angles or sides congruent.
What is a scalene triangle?
300
This polygon, if it's regular, has rotational symmetry at 60, 120, 180, 240, 300, and 360 degrees.
What is a hexagon?
300
This process enlarges or reduces the size of a polygon, creating similar figures.
What is dilation?
300
If a figure is reflected in the x-axis, this is the only coordinate that changes.
What is the y-coordinate?
400
These angles share a vertex, have sides that are parts of the same two lines, and are always congruent.
What are vertical angles?
400
This type of quadrilateral has all the properties of parallelograms, rectangles, and rhombuses.
What is a square?
400
A stop sign is an example of this type of polygon -- be specific.
What is a regular octagon?
400
If any triangle falls into this category, it is similar with all other triangles of this type.
What is an equilateral triangle?
400
If the point (-3, 4) is translated by the notation (x + 5, y - 3), these will be the new coordinates.
What are (2, 1)?
500
The two acute angles in a right triangle always have this relationship, as they must add up to 90 degrees.
What is complementary?
500
This triangle has at least two angles congruent.
What is an isosceles triangle?
500
The Department of Defense in Washington, DC, is housed in a building that has this shape.
What is a (regular) pentagon?
500
The corresponding sides of similar figures don't have to be congruent, but they do have to have this relationship.
What is proportional?
500
When a point is moved from (-4, 1) to (4, -1), it could have been rotated by this number of degrees.
