Exploring Basic Rigid Transformations in Desmos

What is the main idea behind using transformations to show congruence?

• To create a new shape

• To change the size of the shape

• To map one shape onto another so that all points align

• To change the color of the shape

Which transformation involves adding or subtracting values to the coordinates of a shape?

• Dilation

• Translation

• Rotation

• Reflection

What happens to a shape when it is reflected across the y-axis?

• It moves down

• It moves up

• It flips vertically

• It flips horizontally

Reflecting a shape across the x-axis results in which of the following?

• The shape flips vertically

• The shape moves to the left

• The shape moves to the right

• The shape flips horizontally

What is the result of reflecting a shape across the line y=x?

• The shape flips vertically

• The shape flips horizontally

• The shape rotates 90 degrees

• The shape reflects diagonally

How does a 90-degree rotation affect the position of a shape?

• It flips the shape vertically

• It rotates the shape to the next quadrant

• It moves the shape to the right

• It moves the shape to the left

What happens to a point on the line of reflection during a reflection transformation?

• It stays in the same position

• It flips vertically

• It moves to a new position

• It flips horizontally

Reflecting a shape across the line y=-x results in which of the following?

• The shape reflects diagonally

• The shape flips vertically

• The shape flips horizontally

• The shape rotates 180 degrees

What is the effect of a 180-degree rotation on a shape?

• The shape flips horizontally

• The shape remains unchanged

• The shape flips vertically

• The shape rotates to the opposite quadrant
