Understanding Translations and Transformations

This tutorial explains mapping rules for translations, focusing on how coordinates change when a shape is moved on a plane. Using triangle ABC as an example, the tutorial demonstrates how to write mapping rules by subtracting or adding values to the x and y coordinates. It also covers different scenarios, such as moving only horizontally or vertically, and concludes with variations in mapping rules.

What is the primary focus of this tutorial?

• Mapping rules for rotations

• Mapping rules for translations

• Mapping rules for dilations

• Mapping rules for reflections

Which of the following is NOT a type of transformation mentioned?

• Scaling

• Reflection

• Rotation

• Translation

How can you identify the image of a shape in a transformation?

• By its position

• By the primes on its vertices

• By its size

• By its color

What is the original coordinate of point A?

• (1, -6)

• (7, -3)

• (-3, 1)

• (3, -1)

What operation is primarily used in translations?

• Addition and Subtraction

• Exponentiation

• Division

• Multiplication

How much is subtracted from the x-coordinates in the given translation?

• 4

• 2

• 6

• 8

What happens to the y-coordinates in the translation?

• They are multiplied by 2

• They are increased by 2

• They remain the same

• They are decreased by 2

What does the mapping rule x - 6, y + 2 indicate?

• Move right 6, up 2

• Move left 6, down 2

• Move right 6, down 2

• Move left 6, up 2

What does a positive change in y indicate in a mapping rule?

• Movement downwards

• Movement to the right

• Movement to the left

• Movement upwards

If a translation only moves right, what happens to the y-coordinate?

• It is multiplied

• It increases

• It remains the same

• It decreases
