Geometric Reflections

Front

What is a reflection?

Back

When you flip or mirror an object across a line.

Front

State the line of reflection: Reflection across y-axis, Reflection across x-axis, Reflection across x = 1, Reflection across y = 1

Back

Reflection across x-axis

Front

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

Back

(1, 4)

Front

Which answer shows a reflection across the x-axis? Options: d, c, b, a

Back

c

Front

What is the Algebraic Notation for this Reflection? Options: (x, y) → (y, x), (x, y) → (-x, y), (x, y) → (-y, -x), (x, y) → (x, -y)

Back

(x, y) → (x, -y)

Front

Reflect over x-axis. Which point would be at (3, -6)? Options: A, B, C, H

Back

A

Front

Describe the reflection.

Back

Reflection over x = -1

Front

If A(2,5) was reflected over the Y-AXIS, what would the coordinates of A' be?

Back

A'(-2,5)

Front

If F(-2,4) was reflected over the Y-AXIS, what would the coordinates of F' be?

Back

F'(2,4)

Front

A line that acts as a mirror so that corresponding points are the same distance from the mirror.

Back
