8th math Transformations

What is a transformation in geometry?

• A transformation is an operation that moves or changes a shape in some way on a graph, including turning, flipping, or sliding.

• A transformation is a method to calculate the area of a shape.

• A transformation is a technique used to measure angles in geometry.

• A transformation is a process of creating a new shape by combining two existing shapes.

What happens to a shape when the scale factor is greater than one?

• The shape undergoes a reduction.

• The shape remains the same size.

• The shape undergoes an enlargement.

• The shape becomes distorted.

What is the effect of a dilation with a scale factor of 1?

• A dilation with a scale factor of 1 leaves the shape unchanged.

• A dilation with a scale factor of 1 doubles the size of the shape.

• A dilation with a scale factor of 1 reduces the shape to half its size.

• A dilation with a scale factor of 1 flips the shape upside down.

What does dilation mean in the context of transformations?

• A transformation that alters the color of a shape.

• A transformation that alters the size of a shape, either enlarging or reducing it based on a scale factor.

• A transformation that rotates a shape around a point.

• A transformation that reflects a shape over a line.

What does rotation mean in geometry?

• Rotation means to turn a shape around a fixed point.

• Rotation refers to the process of flipping a shape over a line.

• Rotation is the act of enlarging a shape to a larger size.

• Rotation involves moving a shape from one location to another without changing its orientation.

What is the difference between a rotation and a reflection?

• A rotation flips a shape over a line, while a reflection turns it around a point.

• A rotation turns a shape around a point, while a reflection flips it over a line.

• A rotation changes the size of a shape, while a reflection does not affect its size.

• A rotation and a reflection are the same transformation.

What is the relationship between transformations and congruence?

• Transformations create figures of different shapes and sizes.

• Transformations such as translations, rotations, and reflections produce congruent figures, meaning they have the same shape and size.

• Transformations only affect the position of figures without changing their size.

• Transformations can only be applied to two-dimensional figures.

Why are transformations important in geometry?

• They help us understand how shapes relate to one another and how they can be manipulated in space.

• They are only used in advanced mathematics.

• They have no real-world applications.

• They are only relevant for 2D shapes.
