Standard 8.MD.1 - Practice identifying a shape by its name.
Included Skills: Geometry
Angles, triangles and polygons • 1.1 properties of special quadrilaterals and regular polygons (pentagon, hexagon, octagon and decagon) including symmetry properties • 1.2 classifying special quadrilaterals on the basis of their properties • 1.3 angle sum of interior and exterior angles of any convex polygon • 1.4 properties of perpendicular bisectors of line segments and angle bisectors • 1.5 construction of simple geometrical figures from given data (including perpendicular bisectors and angle bisectors) using compasses, ruler, set squares and protractors, where appropriate • 1.6 Use GSP or other dynamic geometry software to explore a given type of quadrilateral (e.g. parallelogram) to discover its properties, e.g. diagonals of a parallelogram bisect each other. • 1.7 Investigate the sum of the interior and exterior angles of polygon and obtain the formulae for them. • 1.8 Recognise symmetric properties (rotational and line symmetry) in some special quadrilaterals and regular polygons. • 1.9 Justify whether a mathematical statement is true or false. • 1.10 Use GSP or other dynamic geometry software to construct and study the properties of the perpendicular bisector of a line segment and the bisector of an angle.
