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.

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.

In this lesson, we will determine when it is impossible to construct a triangle given three lengths.

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.

In this lesson, we will learn how to construct triangles given two sides and an angle.

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.

In this lesson, we will learn to construct kite and rhombuses and identify symmetry in constructions

In this lesson, we will learn to explore diagonals and symmetry in constructions.
