Understanding Rotations in Geometry

What is the direction of rotation when the angle is positive?

• Clockwise

• Counterclockwise

• Upward

• Downward

What should you do if the rotation angle is negative?

• Rotate in the counterclockwise direction

• Rotate in the clockwise direction

• Do not rotate

• Rotate twice

What is the first step in rotating a shape about a point?

• Draw a straight line from the point to each vertex of the shape

• Measure the angle of rotation

• Connect all vertices of the shape

• Draw a circle around the point

What tool is essential for measuring the angle of rotation?

• Protractor

• Compass

• Ruler

• Calculator

How do you determine the length of the new line after rotation?

• It is double the length of the original line

• It is the same length as the original line

• It is a random length

• It is half the length of the original line

What is the significance of the prime symbol in the rotated shape?

• Shows the center of rotation

• Denotes the rotated point

• Marks the midpoint of a line

• Indicates the original point

In the second example, what is unique about the rotation point?

• It is on the triangle

• It is outside the triangle

• It is at the midpoint of a side

• It is at the center of the triangle

What is the angle of rotation in the second example?

• 65 degrees

• 90 degrees

• 45 degrees

• 120 degrees

What happens to point P in the second example after rotation?

• It remains in the same location

• It becomes P prime at a different spot

• It moves to a new location

• It disappears

How do you finalize the rotated shape?

• Connect the new points to form the shape

• Measure all angles again

• Erase the original shape

• Draw a new shape from scratch
