What transformation involves flipping a shape over a mirror line to create a mirror image?

Reflection

When a shape is reflected over a mirror line, the reflected shape is ___ to the original shape.

Congruent

True or False: In a reflection, each point on the original shape is the same distance from the mirror line as its corresponding point on the reflected shape.

True

Fill in the blank: Reflecting an isosceles triangle over a vertical or horizontal mirror line produces another ___ triangle.

Isosceles

What is the main characteristic of a translation transformation?

A translation moves a shape in a straight line without changing its size, shape, or orientation.

In a translation, how does each vertex of the original shape move?

Each vertex moves the same distance and direction.

Riddle: I am a transformation that keeps my shape but moves me straight across the plane. What am I?

Translation

True or False: In a translation, the lines connecting corresponding vertices of the original and translated shapes are not parallel.

False: They are parallel and of equal length.

What type of mirror lines can be used in reflections?

Vertical (parallel to the y-axis) or horizontal (parallel to the x-axis).

Fill in the blank: The reflected shape has the same size and shape but a ___ orientation compared to the original.

Reversed

What is the primary difference between reflection and translation in geometric transformations?

Reflection reverses the shape's orientation, while translation preserves the orientation.

Fill in the blank: Reflection requires a ___ line, whereas translation involves a specified direction and distance.

Mirror

True or False: Both reflection and translation maintain the shape's size and angles.

True

Riddle: I can change your orientation but not your size or angles. What am I?

Reflection

In what scenario might a shape be formed by reflecting a smaller shape over two mirror lines?

When the smaller shape has specific symmetry properties.

Fill in the blank: In translation, the shape moves in a specified ___ and distance.

Direction

What geometric transformation is described as preserving the shape’s orientation?

Translation

True or False: Reflection can occur without a mirror line.

False: Reflection requires a mirror line to define the transformation.

What is the definition of reflection in geometry?

Reflection is a transformation where a shape is flipped over a mirror line, creating a mirror image.

The reflected shape in a reflection transformation is ___ to the original shape.

Congruent

Riddle: I am a transformation that flips shapes and creates mirror images. What am I?
