Transformations Intro

Front

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape in some way to create a new shape.

Front

What are the three main types of transformations?

Back

Translation, Rotation, Reflection.

Front

Define translation in geometry.

Back

Translation is a transformation that moves every point of a shape the same distance in the same direction.

Front

What is rotation in geometry?

Back

Rotation is a transformation that turns a shape around a fixed point called the center of rotation.

Front

Define reflection in geometry.

Back

Reflection is a transformation that flips a shape over a line, creating a mirror image.

Front

What is symmetry?

Back

Symmetry is when one shape becomes exactly like another when you move it in some way, such as flipping or rotating.

Front

What is rotational symmetry?

Back

Rotational symmetry is when a shape can be rotated around a center point and still look the same at certain angles.

Front

What is reflectional symmetry?

Back

Reflectional symmetry is when one half of a shape is a mirror image of the other half.

Front

Give an example of a shape with reflectional symmetry.

Back

A butterfly or a heart shape.

Front

Give an example of a shape with rotational symmetry.

Back

A star or a circle.
