True or false: When a point is reflected across a line of symmetry, it remains the same distance from the line.

True or False: When a figure is reflected over a line of reflection, the new image is congruent to the original.

Reflections over the x-axis change the ____-__________.

Find K' if the figure is reflected across the x-axis

Reflect over x-axis. Which point would be at (3, -6)

What is the line of reflection? 

What is the line of reflection? 

∆QRS contains the points: Q(4, 2) R(5, 1) S(3,7). If the triangle is reflected across the y-axis, what will S' be?

Point C (-5, 4) is reflected over the x-axis. What are the coordinates of C'?

The reflection of J (-1,11) is J' (-1, -11). what is the reflection of D (5, -5) when reflected over the same axis of reflection?

The point (a, b) is reflected over the y-axis, then the x-axis, then the y-axis again, and then the y-axis again. What are the coordinates of the new point?

What is your comfort level with reflections?
