## Chapter 11: Constructions

In this chapter: drawing line segments within specified lengths and ratio, and finding measure of specified parts, constructing geometric shapes with specifications, constructing tangents of a circle

## Chapter 12: Areas Related to Circles

The following is included in this chapter: comparing perimeters of circles and squares to derive areas, finding areas of a circle that can be inscribed within a square, word problems that require drawing a circle in relation to its surroundings and finding the measurements of various parts of the circle, word problems requiring trigonometry to find angles

** **Chapter 13: Surface Area and Volumes

In this chapter, problem-solving is required to find the measurement of sides and edges of shapes, of the surface area and volumes of various shapes, when only certain dimensions are given. Three-dimensional shapes such as a cone, a cylinder, and cubes are covered in this chapter. Word problems are also given where shapes need to be drawn according to specifications and calculate dimensions.

## Chapter 14: Statistics

This chapter covers the calculation of mean, median, mode through simple calculations and word problems.

## Chapter 15: Probability

** **In this chapter, word problems are given to calculate the probability of mutually exclusive and non-exclusive events. In certain cases, specifications are given to calculate the favourable outcome for an event.
