Mathematics Unit 6: Transformations

What are the four types of transformations?

What is the act of "sliding" an object across a plane called?

What is the act of "turning" an object a certain number of degrees called?

What is the act of "mirroring" an object across a line called?

What is the act of "growing" or "shrinking" an object by a specific scale factor called?

What is a pre-image?

What is the class code to join the Desmos Transformation Golf activity?

The Transformation Golf activity is due before the next class.

If the Transformation Golf activity is submitted after the start of the next class, it is worth 0 points.

Describe the two main types of symmetry.

Which type of symmetry requires an object to be mirrored across a line?

Which type of symmetry requires an object to be turned a certain amount of degrees?

What are the two types of transformations that do not change the shape of an object?

A _ changes the size of an object.

Unit 6: Transformations

Day 1: Symmetry and Introduction to Transformations
- Symmetry is like a mirror image.
- An image that looks identical after being turned or flipped is symmetrical.
- Two main types of symmetry:
  - Reflectional symmetry: object mirrored across a line of reflection. Can have multiple lines.
  - Rotational symmetry: shape looks the same after rotating. Includes a degree of rotation (how many degrees the shape must turn).

Day 2: Translation, Reflection, Rotation, and Dilation
- Warm-up: Determine rotational and reflectional symmetry of vowels
- Translation: Sliding an object across a plane in a given direction and distance. Shape and orientation remain the same.
- Reflection: Reflecting an object across a line of reflection. Each point of the image is the same distance from the line as the original. Shape remains the same, orientation changes.
- Rotation: Turning an object around a rotation point by a certain number of degrees. Shapes stays the same, orientation changes.
- Dilation: Changing the size of the object, making it larger (growth) or smaller (shrink). Images and pre-images are similar; the scale factor from a given point is important.

Day 3: Group Activity & Catch-up
- Warm-up: Identify transformations used and order.
- Includes group activities and review of previous days' topics.
