Shape Movements and Transformations

The video tutorial covers Math 8, Unit 1, Lesson 1, focusing on how figures can move in a plane. It begins with an introduction to the concept of moving figures without changing their shape or size. The lesson includes an activity called the 'Triangle Square Dance' to visualize shape movements. The tutorial explains how to describe movements and rotations using terms like slide, turn, and rotate. It concludes with an overview of a homework assignment that involves describing the movement of shapes from one position to another.

Which of the following is a reason why a shape might not belong to a group?

• It is the only shape with a right angle.

• It is the largest shape.

• It is the only shape with a curved side.

• It is the only shape with a color.

In the 'triangle square dance' activity, what is one of the movements a shape can make?

• Sliding to the right

• Growing in size

• Jumping over another shape

• Changing color

What does a 90° turn mean in terms of shape movement?

• The shape changes its size.

• The shape rotates a quarter turn.

• The shape moves in a straight line.

• The shape flips upside down.

How can a shape move without changing its size or shape?

• By rotating around a point

• By sliding up or down

• By increasing its angles

• By changing its color

What is the term used when a shape moves from one position to another without turning?

• Stretch

• Flip

• Rotation

• Slide

In the homework assignment, what is one way to describe the movement from position 1 to position 2?

• The shape changes color.

• The shape moves up.

• The shape shrinks.

• The shape rotates 180°.

What is a possible description for moving a shape from position 2 to position 3?

• The shape grows larger.

• The shape slides to the left.

• The shape rotates counterclockwise.

• The shape flips upside down.

How would you describe a movement that involves a 180° rotation?

• The shape changes its color.

• The shape slides to the right.

• The shape rotates halfway around.

• The shape flips over.

What is the first step in Diego's shape movement sequence?

• Move the shape to the right.

• Rotate the shape 90° clockwise.

• Slide the shape down.

• Flip the shape over.

What tool can be used to help visualize shape movements in the homework assignment?

• Tracing paper

• A calculator

• A ruler

• A protractor
