Naming shapes

Shape names you should know…. Triangles Right angled Scalene – no sides the same length. Isosceles – 2 sides and 2 angles equal. Equilateral – all sides are equal, all angles are 60 degrees.

Quadrilaterals Square – all sides equal, each angle is 90 degrees. Rectangle – 2 pairs of sides equal lengths, each angle is 90 degrees. Rhombus – 2 pairs of parallel sides, all sides equal Parallelogram – 2 pairs of equal parallel sides. Trapezium – one pair of parallel sides Kite Arrowhead

Pentagon – 5 sides.Hexagon – six sides Other shapes…..
