What is a translation in geometry?

Back

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

How do you describe a translation?

Back

A translation is described by the distance and direction in which a shape is moved, typically expressed in terms of left/right and up/down movements.

If a shape is translated 3 units left and 2 units up, what is the overall movement?

Back

The overall movement is a shift of 3 units to the left and 2 units up from the original position.

What does '5 Left' indicate in a translation?

Back

'5 Left' indicates that the shape is moved 5 units to the left along the x-axis.

How can you determine the translation needed to move from one shape to another?

Back

To determine the translation, calculate the difference in the x-coordinates and y-coordinates of the two shapes.

What is the significance of the order of translation movements?

Back

The order of translation movements does not affect the final position of the shape; translations are commutative.

If a shape is translated 4 units up, what is the change in its y-coordinate?

Back

The y-coordinate of the shape increases by 4 units.

What is the effect of translating a shape 0 units left and 0 units up?

Back

Translating a shape 0 units left and 0 units up means the shape remains in the same position.

How do you represent a translation mathematically?

Back

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