FAQ

Q: What are transformations?
A: Transformations are changes made to a shape's position, size, or orientation.

Q: What is congruence?
A: Congruence refers to having the same shape and size.

Q: What is similarity?
A: Similarity refers to having the same shape, but not necessarily the same size.

Q: What are some examples of transformations?
A: Examples of transformations include translation, reflection, rotation, and dilation.

Q: What is translation?
A: Translation is a transformation that moves a shape without changing its size or orientation.

Q: What is reflection?
A: Reflection is a transformation that flips a shape over a line, creating a mirror image.

Q: What is rotation?
A: Rotation is a transformation that turns a shape around a fixed point.

Q: What is dilation?
A: Dilation is a transformation that changes the size of a shape, making it larger or smaller.

Q: What is the difference between congruence and similarity?
A: Congruence means two shapes are exactly the same, while similarity means two shapes have the same shape but can be different in size.

Q: Why are transformations important in math?
A: Transformations help us understand how shapes can change and how they are related to each other.

Q: How can I determine if two shapes are congruent?
A: Two shapes are congruent if they have the same size and shape, and their corresponding sides and angles are equal.

Q: How can I determine if two shapes are similar?
A: Two shapes are similar if their corresponding angles are equal and their corresponding sides are proportional.

Q: What is a dilation factor?
A: A dilation factor is the ratio of the corresponding side lengths in a dilation.

Q: What is the formula for a dilation?
A: The formula for a dilation is (x, y) -> (kx, ky), where (x, y) are the original coordinates and k is the dilation factor.
