Transformations Intro Geometry

Translations, rotations, and reflections are three different types of what?

• Transformations
• Geometry
• Vectors
• Shapes

After a figure has been transformed, we call the new figure the...

• Image

• Different shape

• Figure that moved

• egg head

Which set of directions describes the translation from ABCD to A'B'C'D'?

• translated Down 6, left 3

• rotated Down 3, right 6

• translated Up 3, left 6

• reflected Up 6, right 3

If something is congruent, it has...

• The same angle measurements.

• The same birthday

• Larger side lengths.

• The same transformation.

The mathematical term for the line that you reflect a shape over is the...

• Mirror
• Reflective tape
• Line that you reflect over
• Line of reflection

What is the best description for why two shapes are congruent after a reflection?

• They aren't.

• It's the same shape just rotated

• The sides and angles do not change when you reflect.

• Because it just is. Sheesh.

Which type of Transformation will not change the orientation of an object?

• translation, dilation, rotation, reflection

• Reflection, translation

• reflection, dilation, translation

• translation, dilation

A rotation will...

• maintain congruence, but change the area of a shape

• maintain perimeter, but change orientation of a shape

• maintain the same side lengths, but change the perimeter

• will not maintain congruence

What symbol is used to show that two things are congruent?

• ≠
• ≅
• ≡
• =
