Front

What is Rotation in geometry?

Back

Rotation refers to turning a shape around a fixed point, known as the center of rotation.

Front

What is the 270°/90°CC Rotation rule?

Back

The 270° clockwise or 90° counterclockwise rotation rule is given by the transformation: @@(x, y) ightarrow (-y, x)@@.

Front

What is the Translation Rule in geometry?

Back

The Translation Rule describes how to move a shape without rotating or flipping it, represented as: @@(x, y) ightarrow (x+a, y+b)@@.

How is Slope defined in mathematics?

Back

Front

What is the 180° Rotation rule?

Back

The 180° rotation rule is represented by the transformation: @@(x, y) ightarrow (-x, -y)@@.

Front

What does 'Translation' mean in geometry?

Back

Translation means moving every point of a shape the same distance in the same direction.

Front

What is the formula for calculating the slope of a line?

Back

Front

What is a 'turn' in the context of transformations?

Back

A 'turn' refers to a rotation of a shape around a fixed point.

Front

What does the term 'x-intercept' refer to?

Back

The x-intercept is the point where a line crosses the x-axis, meaning y=0.

Front

What does the term 'y-intercept' refer to?

Back

The y-intercept is the point where a line crosses the y-axis, meaning x=0.
