PLS HELP ME!! What is the difference between a rotation and a reflection?

What does it mean for two figures to be congruent?

Travis performs a dilation of ⅓ on a polygon. He then classifies the image and pre-image as being congruent. Is Travis correct? Why or why not?

What does it mean for angles to be adjacent?

If angle X has a measure of 40 degrees and angle Y is vertical to angle X, what is the measure of angle Y?

Triangle ABC has two known angles. Angle A measures 55 degrees. Angle B measures 30 degrees. What is the measure of angle C?

rotation spins the shape around the origin while a reflection mirrors it across an axis. Two congruent figures are two figures that are Identical but in different locations. Travis is incorrect because when Travis changes the size he changes the shapes from being congruent to being similar. Adjacent angles are angles that share a wall and a vertex. The measure of angle y is 40 degrees. The measure of angle C is 95 degrees.

Step-by-step explanation:

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1
