Level 10 Mathematics

Students will learn how triangles can be classified by side length and by angles. The different types of convex quadrilaterals are named and illustrated.

Using examples from the natural world, students learn about similarity, ratio and proportion. Students will learn to survey to find the width of a river and use a mirror to find the height of a tall object.

Key concepts of angles are introduced such as defining and writing information about an angle, mathematical notation for rays, line segments and lines. Other topics introduced include obtuse angles, acute angles and congruent angles.

A teen girl creates a mobile to hang above a baby's crib by using the following: bisecting an angle, perpendicular bisector of a line, construct a triangle, determine the centre of gravity, determine the inscribed circle of a triangle and determine the circumcircle of a triangle.

The first quadrant of the Cartesian plane is explored in the context of a city street grid. Other features include using coordinates, graphing relationships and how slope is measured.
