Rigid Transformations
These transformations preserve distance and angle measures.
What are Rigid Transformations?
When two lines intersect, two angles across from each other that are congruent.
What are Vertical Angles?
The sum of the interior angles of any triangle.
What is 180 degrees?
True or False: A triangle with side lengths 3 cm, 4 cm, and 8 cm is possible.
What is false?
A line that cuts through two parallel lines.
What is a transversal?
This transformation slides a figure without rotating or flipping it.
What is a translation?
These angles are in the same matching corner when two parallel lines are cut by a transversal.
What are corresponding angles?
A triangle with one 90 degree angle.

What is 67?
A transformation that turns a figure around a fixed point.
What is a rotation?
Angles that add up to 180° and lie on the same side of the transversal.
What are same-side interior angles?
Two angles who's sum is 90 degress.
What are complementary angles?
Name a side that would make a triangle with 7 and 8.
What is (2-14)?
(3,-2) reflected over the y-axis.
What is (-3,-2)?
