Transformations

What are the coordinates of the origin in the coordinate plane?

• (0, 0)

• (1, 1)

• (-1, -1)

• (2, 2)

What are the four main types of transformations?

• Translation, rotation, reflection, and dilation.

• Translation, scaling, shearing, and rotation.

• Reflection, rotation, projection, and translation.

• Dilation, inversion, rotation, and translation.

What is the center of rotation?

• The point where all lines intersect in a shape.

• The fixed point around which a shape is rotated.

• The midpoint of the shape's longest side.

• The point at which the shape's area is maximized.

What is a transformation in geometry?

• A transformation is an operation that moves or changes a shape in some way on a coordinate plane.

• A transformation is a method to calculate the area of a shape.

• A transformation is a technique used to measure angles in geometry.

• A transformation is a way to classify shapes based on their properties.

What are coordinates?

• A set of values that show an exact position on a coordinate plane, typically represented as (x, y).

• A method of measuring distances between points on a map.

• A type of graph used to display data visually.

• A system for organizing information in a database.

What is the line of reflection?

• The line over which a shape is flipped to create a mirror image.

• A line that divides a shape into two equal parts without flipping.

• A line that connects two points on a shape.

• A line that represents the axis of rotation.

What is a dilation in geometry?

• A transformation that changes the size of a shape but keeps its proportions the same.

• A process that rotates a shape around a point.

• A method to reflect a shape across a line.

• A technique to translate a shape to a different location.

What is a reflection?

• A transformation that flips a shape over a line, creating a mirror image.

• A process of bending light to create a rainbow.

• A method of rotating a shape around a point.

• A technique for enlarging a shape without changing its proportions.

What is a rotation?

• A transformation that turns a shape around a fixed point, called the center of rotation.

• A process of flipping a shape over a line to create a mirror image.

• A method of enlarging or reducing a shape while maintaining its proportions.

• A technique for sliding a shape from one position to another without changing its size.

What is the effect of a 90-degree clockwise rotation on a point (x, y)?

• (x, y)

• (y, x)

• (y, -x)

• (-y, x)
