Recall

Shapes and their symmetries — objective 1

Maths4U Original · Short practice

Consider a nonsquare rhombus.

How many lines of symmetry does it have?

Enter one exact number or fraction unless the question specifies rounding. If it asks for a coefficient of π, enter that coefficient only. Give full reasoning separately for written problems.

Shapes and their symmetries — objective 4

Maths4U Original · Short practice

Consider a nonequilateral isosceles triangle.

Find its smallest positive angle of rotational symmetry in degrees.

Enter one exact number or fraction unless the question specifies rounding. If it asks for a coefficient of π, enter that coefficient only. Give full reasoning separately for written problems.

Shapes and their symmetries — objective 4

Maths4U Original · Short practice

Consider a parallelogram that is neither a rectangle nor a rhombus.

Find its smallest positive angle of rotational symmetry in degrees.

Enter one exact number or fraction unless the question specifies rounding. If it asks for a coefficient of π, enter that coefficient only. Give full reasoning separately for written problems.
