Transformations and Reflections in Geometry

The video tutorial covers three types of geometric transformations: translations, reflections, and rotations. It begins with an overview of these transformations, followed by detailed explanations and examples for each. Translations involve sliding a figure, reflections involve flipping a figure over a mirror line, and rotations involve turning a figure around a center point. The video concludes with a reminder to check congruency and offers additional resources for further learning.

What is another name for the transformation known as translation?

• Turn

• Mirror

• Flip

• Slide

When translating a figure, what must remain unchanged?

• The orientation of the figure

• The color of the figure

• The position of the figure

• The size and shape of the figure

In a reflection, what is the line called that acts as a mirror?

• Reflection line

• Mirror line

• Line of symmetry

• Axis of symmetry

What must be true about the distance between a point and its image in a reflection?

• The distance must be twice the length of the mirror line

• The distance must be equal on both sides of the mirror line

• The distance must be equal to the length of the mirror line

• The distance must be zero

What should you check after performing a reflection?

• If the figure is congruent to its image

• If the figure is colored differently

• If the figure is rotated

• If the figure is larger

What is the key point called around which a figure is rotated?

• Pivot point

• Rotation center

• Axis of rotation

• Central point

How many degrees is a quarter turn in a rotation?

• 360 degrees

• 180 degrees

• 90 degrees

• 45 degrees

What is the result of a 180-degree rotation of a figure?

• The figure is rotated to the opposite side

• The figure is unchanged

• The figure is mirrored

• The figure is flipped upside down

Which transformation involves a figure swinging around a point?

• Rotation

• Scaling

• Translation

• Reflection
