Transformations in Geometry

Mr. Duffek introduces transformations in I Excel L1, focusing on translation, reflection, and rotation. He explains how to identify these transformations through examples and discusses combinations of transformations. The video concludes with a summary of the key concepts covered.

What are the three main types of transformations discussed in the I Excel tutorial?

• Translation, Reflection, Rotation

• Reflection, Scaling, Shearing

• Rotation, Shearing, Translation

• Translation, Scaling, Rotation

Which transformation involves sliding a shape without changing its orientation?

• Reflection

• Translation

• Rotation

• Scaling

How can you identify a translation in a problem?

• The shape flips over a line

• The shape changes size

• The shape slides without changing orientation

• The shape rotates around a point

What transformation is characterized by a shape maintaining its orientation while moving?

• Rotation

• Reflection

• Scaling

• Translation

What is a key characteristic of a reflection transformation?

• The shape slides to a new position

• The shape rotates around a point

• The shape changes size

• The shape flips over a line

In a reflection, what is the line called over which the shape flips?

• Line of translation

• Axis of rotation

• Line of reflection

• Line of symmetry

Which transformation involves a shape flipping over a specific line?

• Reflection

• Rotation

• Scaling

• Translation

Which transformation involves turning a shape around a fixed point?

• Reflection

• Rotation

• Translation

• Scaling

What is the fixed point called around which a shape rotates?

• Center of scaling

• Axis of translation

• Point of rotation

• Center of reflection

How can you distinguish a rotation from a reflection?

• A rotation involves sliding the shape

• A rotation involves turning the shape around a point

• A rotation involves flipping the shape

• A rotation involves changing the size of the shape
