Exploring Rigid Transformations

The video tutorial covers rigid transformations on a coordinate plane, including translation, reflection, and rotation. It provides step-by-step instructions for moving a triangle through these transformations, with pauses for viewers to practice and check their work. The tutorial emphasizes maintaining the shape's size while changing its position and concludes with a reflection exercise and encouragement to continue learning.

What does a rigid transformation affect in a shape on a coordinate plane?

• The texture

• The position only

• The color

• The size and shape

Which transformation does not alter the size of a shape?

• Reflection

• Scaling

• Translation

• Both translation and reflection

What is the result of translating a triangle by x - 4 and y + 2?

• Moves right 4 and down 2

• Moves left 4 and down 2

• Moves left 4 and up 2

• Moves right 4 and up 2

What are the new coordinates of point A after the triangle is translated?

• x = -1, y = 6

• x = -3, y = 3

• x = -3, y = 6

• x = 0, y = 2

What does a 90° clockwise rotation around a point imply?

• The shape rotates around the point without changing its location

• The shape enlarges

• The point moves 90°

• The shape flips over

How does the position of point B change after a 90° clockwise rotation?

• It moves down

• It moves to the right

• It moves to the left

• It stays the same

After translating a triangle down by 5 units, what is the new y-coordinate of point B?

• -3

• 1

• -2

• 0

What is the new y-coordinate of point C after translating the triangle down by 5 units?

• 1

• -6

• -1

• 0

What is the effect of reflecting a shape across a vertical line x = 2?

• It moves 2 units to the right

• It disappears

• It flips over the line

• It rotates around the line

After reflecting the triangle across x = 2, what is the new x-coordinate of point C?

• 7

• 2

• 5

• 0
