Translation Effects

Translation Effects

Learning Target

• I can determine the effects translations have on coordinates of a figure.

Translating Figures

• Translate the rectangle 2 units right and 3 units up. Find Point B'

• 1) Count by units to find B'

• 2) Use an algebraic formula

• ( x + 2, y + 3)

• ( 2 + 2, 3 + 3)

• B' ( 4, 6 )

Multiple Choice

Translate Point Q, 5 units right and 1 unit up. What are the coordinates of Point Q'?

• ( 3, 2 )

• ( 6, -1 )

• ( -6, 1 )

• ( 2, -3 )

Multiple Choice

Translate the figure 1 unit left and 2 units up. What are the coordinates of Point A'?

• ( 4, 7 )

• ( 6, 3 )

• ( 7, 4 )

• ( 3, 6 )

Determine the Rule

• Identify pre-image vs image

• How many units did the figure move left/right?

• How many units did the figure move up/down?

• Algebraic Rule: ( x - 3, y + 4 )

Multiple Choice

Determine the rule to describe the translation.

• ( x + 4, y - 3 )

• ( x + 2, y + 3 )

• ( x - 5, y + 3 )

• ( x - 3, y + 6 )

Multiple Choice

Determine the rule to describe the translation.

• ( x - 2, y - 4 )

• ( x + 1, y + 4 )

• ( x - 1, y )

• ( x + 4, y + 2 )
