Geometric Transformations and Properties

The video tutorial covers geometric transformations, including reflection, rotation, translation, and dilation. It explains how these transformations affect shapes, focusing on maintaining or altering size and orientation. The concept of isometric transformations, where the size and shape remain unchanged, is also discussed.

Which of the following is NOT a type of geometric transformation discussed in the introduction?

• Reflection

• Translation

• Scaling

• Rotation

What is the term used for the original shape before a reflection?

• Image

• Pre-image

• Reflection

• Mirror image

In a reflection, what is the line called over which the object is flipped?

• Mirror line

• Line of reflection

• Flip line

• Axis of symmetry

During a rotation, around what does the object turn?

• An axis

• A point

• A plane

• A line

Which of the following is true about rotation?

• It involves flipping the object.

• It changes the size of the object.

• It slides the object to a new position.

• It turns the object around a point.

What remains unchanged during a translation?

• The shape of the object

• The color of the object

• The position of the object

• The size and orientation of the object

Which transformation involves moving an object without rotating it?

• Reflection

• Rotation

• Translation

• Dilation

What happens to an object during dilation?

• It changes size while maintaining its shape.

• It is turned around a point.

• It is flipped over a line.

• It slides to a new position.

Which transformation is NOT considered isometric?

• Rotation

• Dilation

• Reflection

• Translation

What is an isometric transformation?

• A transformation that changes the size of an object

• A transformation that maintains the size and shape of an object

• A transformation that flips an object

• A transformation that rotates an object
