What is a translation in geometry?

Back

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

How do you describe a translation of a shape?

Back

A translation can be described by how far and in which direction the shape moves, typically using coordinates (x,y) to indicate the movement.

What does it mean to reflect a shape across the y-axis?

Back

Reflecting a shape across the y-axis means flipping the shape over the y-axis, resulting in a mirror image on the opposite side.

How do you determine the new coordinates of a point after a translation?

Back

To determine the new coordinates after a translation, you add the translation values to the original coordinates.

What is the x-axis?

Back

The x-axis is the horizontal axis in a coordinate plane, where the y-coordinate is zero.

What is the y-axis?

Back

The y-axis is the vertical axis in a coordinate plane, where the x-coordinate is zero.

What is the effect of translating a point 5 units to the right and 8 units down?

Back

Translating a point 5 units to the right increases the x-coordinate by 5, and translating it 8 units down decreases the y-coordinate by 8.

What are the coordinates of point A' if point A(2, 5) is translated by (x,y) --> (x+3, y-2)?

Back

The new coordinates of point A' would be (5, 3).

What is the definition of a trapezoid?

Back

A trapezoid is a four-sided figure (quadrilateral) with at least one pair of parallel sides.
