We need to know the reflection rules! Draw your reflections out if you don't remember!

Multiple Choice

Which answer shows a reflection across the x-axis?

• d
• c
• b
• a

Multiple Choice

If the triangle is reflected across the y-axis, the coordinates of the new triangle will be (5, 0), (2, 3), and ___.

• (0, 5)

• (4, 3)

• (3, 5)

• (2, 3)

We need to memorize these rules!
