Geometry Unit 1 End Review

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal in measure.

Front

Which angles are vertical angles in the following set: 8 and 4, 2 and 5, 7 and 1?

Back

The vertical angles are 8 and 4.

Front

What is reflection symmetry?

Back

Reflection symmetry occurs when a shape can be divided into two identical halves that are mirror images of each other.

Front

Does this shape have reflection symmetry? (Yes/No)

Back

Yes.

Front

What is rotation symmetry?

Back

Rotation symmetry exists when a shape can be rotated around a central point and still look the same at certain angles.

Front

Does this shape have both reflection and rotation symmetry? (Both/Neither/Just Reflection/Just Rotation)

Back

Both.

Front

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape in some way, such as translation, rotation, or reflection.

Front

What is a translation?

Back

A translation is a transformation that moves a shape from one location to another without changing its size, shape, or orientation.

Front

What is a reflection?

Back

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

Front

What is a rotation?

Back

A rotation is a transformation that turns a shape around a fixed point at a certain angle.
