Transformations in Geometry

Miss Griffin introduces unit 3 skill 1, focusing on identifying single transformations. The video covers key vocabulary, including pre-image, image, and rigid motion, and explains four types of transformations: translation, reflection, rotation, and dilation. Each transformation is described with its notation and whether it preserves distance and angle measure. The video includes examples and practice questions to reinforce understanding.

What is the primary focus of Unit 3 Skill 1?

• Identifying multiple transformations

• Identifying single transformations

• Identifying transformations in 3D

What does the term 'pre-image' refer to in transformations?

• The final figure after transformation

• The original figure before transformation

• The axis of transformation

• The midpoint of a transformation

Which of the following is preserved in a rigid motion?

• Speed and direction

• Volume and mass

• Distance and angle measure

• Color and texture

What is the key characteristic of a translation?
