This notation(symbol) is how we differentiate the preimage from the image.
What is prime?
A line that cuts across two or more (usually parallel) lines then create multiple angles.
What is a Transversal?
The figure has been reflected over this line.
What is the x-axis?
Angles that are opposite and congruent
What are vertical angles?
The given graph depicts rigid transformations of the pre-image *. This triangle represents a Rotations of * 90-degrees counterclockwise about the origin.
What is figure B?
A pair of angles whose sum is 90 degrees.
What are complementary angles?
This is the image coordinate pair when the preimage (1, 6) is translated to the left 3 and down 1.
What is (-2, 5)?
Two angles on the exterior of the parallel lines but opposite of the transversal. Their measures are congruent.
What are alternate exterior angles?
These two transformations have occurred to the given figure.
What is a Reflection across the x-axis and then translated 10 units right and 2 units up.?
Two angles that are on the inside of the parallel lines and the same side of the transversal. Their measures are supplementary.
What are same side interior angles?
