The video tutorial covers practice problems for lesson seven, focusing on rigid transformations. It explains the concept of rigid transformations, where angles and side lengths remain unchanged, and analyzes various problems involving transformations such as translation, rotation, and reflection. The tutorial provides step-by-step guidance on identifying and performing these transformations, emphasizing the importance of maintaining congruence in shapes.

What is a key characteristic of a rigid transformation?

• Angles and side lengths change

• Only angles change

• Only side lengths change

• Angles and side lengths remain the same

Why is the transformation from P to Q not considered rigid?

• The angles remain the same

• The transformation is a reflection

• The side lengths remain the same

• The angles change

How is triangle A transformed to triangle B?

• By sliding up 2 units and right 3 units

• By rotating 90 degrees

• By reflecting over the x-axis

• By scaling up by a factor of 2

What remains unchanged in a rigid transformation?

• The orientation of the shape

• The angles and side lengths

• The position of the shape

• The color of the shape

Why is the transformation from A to B not rigid in the third problem?

• The transformation is a rotation

• The angles change

• The side lengths change

• The shape is reflected

What is the result of translating a shape to its prime position?

• A scaled copy

• A translated copy

• A reflected copy

• A rotated copy

What is a prism in the context of translations?

• A scaled shape

• A translated copy of the base

• A reflected shape

• A rotated shape

How do you perform a 180-degree rotation around a point?

• By moving the shape to the left

• By drawing a straight line through the point and locating the shape on the opposite side

• By reflecting the shape over the y-axis

• By scaling the shape down

What is the first step in reflecting an image over a line?

• Drawing lines parallel to the line of reflection

• Drawing lines perpendicular to the line of reflection

• Scaling the image by a factor of 2

• Rotating the image 90 degrees

How can you verify the accuracy of a reflection?

• By checking if the image is larger

• By scaling the image down

• By rotating the image 180 degrees

• By ensuring the reflected points are equidistant from the line of reflection
