What is the centre of rotation?

• The point around which you reflect an object

• The point around which you rotate an object

• The point where the x-axis and y-axis intersect

• The point at the center of a shape

What are coordinates used for?

• To calculate the area of a shape

• To measure the size of an angle

• To determine the position of a point in space

• To find the line of symmetry

What is a degree?

• A unit of measure for the size of a point

• A unit of measure for the distance between two points

• A unit of measure for the size of an angle

• A unit of measure for the length of a line

What is the line of symmetry?

• A line that divides an object into two equal parts

• A line that reflects an object

• A line around which an object rotates

• A line that marks the position of an object

What does a mirror line do in geometry?

• It reflects an object

• It rotates an object

• It enlarges a shape

• It moves an object in any direction

What is reflection in geometry?

• A transformation that changes the size of an object

• A transformation resulting in a mirror image

• A movement of an object without rotating it

• A change in the position and orientation of a shape

What is rotation in geometry?

• A change in the position and orientation of an object

• A transformation resulting from turning an object around a centre point

• A transformation that enlarges a shape

• A movement of an object without changing its size

What is a transformation in geometry?

• A change of the size of an object only

• A change of the position, orientation, and/or size of an object using rotation, reflection, enlargement, or translation

• A change of the position of a point

• A change of the shape of an object only

What does translation do in geometry?

• It moves an object in any direction without rotating it

• It changes the size of an object

• It reflects an object over a mirror line

• It rotates an object around a centre point

What are vectors used for?

• To reflect an object

• To measure the size of an angle

• To move an object by indicating both magnitude and direction

• To rotate an object around a point
