Transformations in Geometry

Mr. Crawford introduces transformations in geometry, covering translation, reflection, and rotation. He provides examples and exercises for each type, demonstrating how to perform these transformations on figures. The video includes practical exercises on translating, reflecting, and rotating figures, helping students understand the concepts and apply them to geometric problems.

What is a transformation in geometry?

• A change in the size of a figure

• A movement of a figure to a new location

• A change in the shape of a figure

• A change in the color of a figure

Which transformation slides a figure in a straight line?

• Reflection

• Rotation

• Translation

• Dilation

What does a reflection transformation create?

• A translated image

• A rotated image

• A mirror image

• A scaled image

What is the key characteristic of a reflection?

• It changes the size of the figure

• It creates a mirror image

• It rotates the figure around a point

• It slides the figure to a new position

In a rotation transformation, what is the fixed point called?

• Center of rotation

• Center of reflection

• Center of translation

• Center of dilation

What is the key characteristic of a rotation?

• It changes the size of the figure

• It slides the figure to a new position

• It rotates the figure around a point

• It reflects the figure over a line

What is the result of reflecting a figure over a line?

• A scaled figure

• A translated figure

• A rotated figure

• A mirror image

How many degrees is the figure rotated in the example?

• 45 degrees

• 90 degrees

• 180 degrees

• 360 degrees

What happens to a figure during a translation?

• It is reflected over a line

• It is rotated around a point

• It changes size

• It slides to a new position

What is the key characteristic of a translation?

• It changes the size of the figure

• It reflects the figure over a line

• It slides the figure to a new position

• It rotates the figure around a point
