Symmetry
Math ⇒ Geometry
Symmetry starts at 6 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Symmetry.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 12
A context: A logo is designed in the shape of a regular octagon. The designer wants to add a line of symmetry. How many different lines of symmetry can be drawn through the center of the logo?
A function f(x) is said to be even if f(-x) = f(x) for all x in its domain. Is the function f(x) = cos(x) even, odd, or neither?
A regular hexagon has how many lines of symmetry?
A regular pentagon is rotated about its center. What is the smallest angle of rotation that maps the pentagon onto itself?
A regular polygon has 15 sides. What is the smallest angle of rotation that maps it onto itself?
Describe the difference between reflectional symmetry and rotational symmetry.
Describe the symmetry of the graph of y = sin(x).
Determine the order of rotational symmetry for a regular decagon.
Explain why a scalene triangle has no symmetry.
Explain why the graph of y = |x| is symmetric with respect to the y-axis.
If a figure has 8 lines of symmetry and rotational symmetry of order 8, what is the most likely shape?
If a regular polygon has an interior angle of 150°, how many lines of symmetry does it have?
