Discuss the following geometric transformations: reflection, translation, dilation, and rotation.
Understand the Problem
The question asks for a discussion of four geometric transformations: reflection, translation, dilation, and rotation. This involves explaining what each transformation does to a geometric figure in terms of its position, size, and orientation.
Answer
Geometric transformations include reflection (flip), translation (slide), dilation (resize), and rotation (turn).
Geometric transformations alter a shape's position or size. The main types are:
- Reflection: A flip over a line.
- Translation: Sliding a shape.
- Dilation: Enlarging or reducing size.
- Rotation: Turning around a point.
Answer for screen readers
Geometric transformations alter a shape's position or size. The main types are:
- Reflection: A flip over a line.
- Translation: Sliding a shape.
- Dilation: Enlarging or reducing size.
- Rotation: Turning around a point.
More Information
Reflections, translations, and rotations are rigid transformations that preserve shape and size, while dilation is non-rigid and changes the size.
Tips
A common mistake is confusing the different types of transformations. Remember: reflection is a flip, translation is a slide, dilation is a resize, and rotation is a turn.
