Exploring Adding and Subtracting Rational Expressions

What defines line symmetry in a figure?

• If it looks the same when viewed from a mirror

• If it can be rotated less than 360 degrees and still look the same

• If it can be divided into two identical halves by a line

• If it looks the same when rotated 180 degrees

Can line symmetry be horizontal?

• Yes, but only in circles

• No, it can only be diagonal

• No, it must always be vertical

• Yes, it can be horizontal, vertical, or at an angle

What is point symmetry?

• Symmetry when a figure looks the same in a mirror reflection

• Symmetry when a figure can be divided into two identical halves

• Symmetry when a figure looks the same after a 180-degree rotation

• Symmetry around a central point after a 360-degree rotation

Which figure typically demonstrates point symmetry?

• Circle

• Square

• Letter 'N'

• Rectangle

What is rotational symmetry?

• When a figure looks the same after rotating less than 360 degrees

• When a figure can be divided into two identical halves

• When a figure looks the same after a 180-degree rotation

• When a figure looks the same in a mirror reflection

Does point symmetry imply rotational symmetry?

• No, never

• Only in circles

• Only in squares

• Yes, always

Which of the following does NOT necessarily have rotational symmetry?

• A square

• A circle

• A rectangle

• An equilateral triangle

What type of symmetry does a regular pentagon have?

• Line and point

• Line, point, and rotational

• Point and rotational

• Line and rotational

Which number has point symmetry but not line symmetry?

• 8

• 0

• 2

• None of the above

How can you determine if a figure has rotational symmetry?

• By checking if it has a mirror image

• By rotating it less than 360 degrees to see if it looks the same

• By rotating it 180 degrees to see if it looks the same

• By dividing it into two identical halves
