Exploring circles
In this lesson, we will learn to name the basic features of circles and reasoning using their reasoning using their properties. We will also draw circles using pair of compasses.

Constructing triangles
In this lesson, we will learn how to construct triangles using a pair of compasses and ruler given the length of the sides. We will need a pair of compasses, pencil and ruler for this lesson.
Impossible triangles
In this lesson, we will determine when it is impossible to construct a triangle given three lengths.
Drawing Similar Triangles
In this lesson, we will learn to draw triangles with the same interior angles using a protractor. We will also discuss the properties of similar triangles.
Triangle constructions
In this lesson, we will learn how to construct triangles given two sides and an angle.
Quadrilaterals in circles
In this lesson, we will learn to form quadrilaterals using the properties of circles. We will also learn to use symmetrical properties of special quadriaterals.
Constructing quadrilaterals
In this lesson, we will learn to construct kite and rhombuses and identify symmetry in constructions
Further constructions
In this lesson, we will learn to explore diagonals and symmetry in constructions.
