Knowing the properties of of 2D shapes is basic but important skill. Depending on if the shapes are equilateral, their properties may vary. Underneath, we have explained the properties for as many types of this shape as possible.
•4 equal sides•4 equal angles (90°)•4 axes of symmetry
Rectangle
•2 sets of 2 equal sides•4 equal angles (90°)•2 axes of symmetry
Triangle
•Can have no, 2 or 3 equal sides•Can have no, 2 or 4 equal angles•Can have up to 2 axes of symmetry
Circle
•Constant diameter and radius•Almost infinite axes of symmetry going through the centre
Pentagon
•5 sides (can be equal)•5 angles (can be equal)•Can have up to 5 axes of symmetry
Hexagon
•6 sides (can be equal)•6 angles (can be equal)•Can have up to 6 axes of symmetry
Octagon
•8 sides (can be equal)•8 angles (can be equal)•Can have up to 8 axes of symmetry
Parallelogram
•2 sets of 2 equal sides•2 sets of 2 equal angles•Usually no axes of symmetry
Rhombus
•All sides the same length•2 sets of 2 equal angles•2 lines of symmetry
Trapezium
•At least 2 parallel sides•Can have pairs of equal angles•Can have a line of symmetry
