Translations

Front

What is a translation in geometry?

Back

A translation is a type of transformation that moves every point of a shape or object a certain distance in a specified direction.

How do you represent a translation mathematically?

Back

A translation can be represented as (x, y) -> (x + a, y + b), where 'a' is the horizontal shift and 'b' is the vertical shift.

What does it mean to translate a shape 5 units left and 1 unit up?

Back

It means to move the shape 5 units in the negative x-direction and 1 unit in the positive y-direction.

When translating an object, how does the 'x' coordinate change when moving right?

Back

The 'x' coordinate increases by the number of units moved to the right.

If a shape is translated 5 units right and 2 units down, what are the changes to its coordinates?

Back

The new coordinates will be (x + 5, y - 2).

How do you describe the translation from a pink shape to a blue shape if it involves moving left and up?

Back

You would describe it as moving 5 units left and 2 units up.

What is the effect of translating a shape on its size and orientation?

Back

Translation does not change the size or orientation of the shape; it only changes its position.
