What are the two directions you can rotate a figure?
clockwise and counterclockwise
________________ angles are two angles that equal 90°.
2. ________________ angles are two angles that equal 180°.
1. Complementary
2. Supplementary
True or False: A figure is congruent to another if it can be moved with translations, rotations, and reflections to fit exactly over the other.
True!
What kind of angles are angle 5 and angle 8?
Supplementary!!
A _____________ is a transformation that “flips” a figure over a line. Every point on the figure moves to a point directly on the opposite side of the line. The new points are the same distance from the line as they are in the original figure.
reflection
Two angles that share a vertex but not a side and have the same measurement are called ____________ angles. (Hint: They form a bowtie shape)
vertical
Are the following figures congurent? EXPLAIN YOUR ANSWER.
No they are not congruent. The shapes of both figures are different and will not fit one another.
What kind of angles are angle 1 and angle 3?
Vertical!
A _____________ is a transformation that “turns” a figure, where every point on the figure moves around a center by a given angle in a specific direction.
rotation
Two angles that are on the same side of the transversal, but on different lines and have the same measurement are called ___________________ angles.
(Hint: They form an F shape)
Corresponding
Are the following figures congruent? EXPLAIN YOUR ANSWER.
Yes, these figures are congruent. Reflect Quadrilateral A across the y axis and then translate one unit to the right and one unit down.
What kind of angles are angle 3 and angle 7?
Corresponding!
A ______________ is a transformation that “slides” a figure, where every point moves in a given distance in a given direction.
translation
Two angles that are formed by a transversal and the lines it crosses, on opposite sides of the transversal, inside the parallel lines and have the same measurement are called _______________________ angles. (Hint: They form a Z shape)
Alternate interior
Are the following figures congurent? EXPLAIN YOUR ANSWER.
No, these figures are not congruent. The angles in both shapes are different.
What kind of angles are angle 4 and angle 6?
Alternate Interior!!
