A line that cuts across two or more parallel lines
What is a transversal
An angle whose measure is less than 90 degrees
Two angles are congruent. The measure of the first angles is 42 degrees, what is the measure of the second angle?
What is 420

What is 1.
Two angles whose measures add up to 180 degrees
What are supplementary angles

When 2 parallel lines are both intersected by a transversal, these angles occupy the same position on the top and bottom parallel lines.
What are Corresponding Angles.
Two lines that form right angles where they intersect
What are perpendicular lines

State the rule for an x-axis reflection
(x, y) --> (x, -y)
True or False:
A rectangle has a perimeter of 18 units. It is rotated 180 degrees, then translated 4 units left. It's perimeter is still 18 units.
True
Congruent angles formed by two intersecting lines
What are Vertical Angles.
Two shapes whose corresponding angles are congruent and whose corresponding sides are in proportion

When 2 parallel lines are both intersected by a transversal these angles are inside of the two parallel lines and on opposite sides of the transversal.
What are Alternate Interior Angles.
In geometry, something that changes the position, orientation, or size of a figure
