Front

What is the arrow notation for the translation of a shape from (x, y) to (x + 6, y - 8)?

Back

(x, y) --> (x + 6, y - 8)

Front

If ∆QRS has points Q(4, -2), R(5, 1), S(3, 7), what is Q' after reflecting across the x-axis?

Back

Q' (4, 2)

Front

Which option represents a reflection across the x-axis?

Back

C

Front

Reflect the point T(2, -4) over the y-axis. What is T'?

Back

T' (-2, -4)

Front

What is a translation in geometry?

Back

A translation is a transformation that moves every point of a shape the same distance in a specified direction.

Front

What happens to the coordinates of a point (x, y) when it is reflected across the x-axis?

Back

The new coordinates will be (x, -y).

Front

What happens to the coordinates of a point (x, y) when it is reflected across the y-axis?

Back

The new coordinates will be (-x, y).

Front

What is the line of symmetry?

Back

A line of symmetry is a line that divides a shape into two identical parts that are mirror images of each other.

Front

If a shape is translated 5 units left and 3 units up, what is the arrow notation for this translation?

Back

(x, y) --> (x - 5, y + 3)
