# Geometry & Construction of 2D Shapes [Foundation]

In this course, we take a look of the properties of two-dimensional shapes and use them to find missing angles or lengths, solving various problems. This is an opportunity to draw on your analytic skills to unpack problems.

## Types of Triangles

We kick off our section of quadrilaterals by distinguishing between equilateral, isosceles, scalene and right-angled triangles, using their properties of sides and angles.

## Properties of Triangles

In the second lesson involving triangles, we will explore additional properties such as exterior and interior angles of triangles. We will also use geometric and algebraic properties to find missing angles.

## Theorem of Pythagoras

In lesson 3, the focus is on right-angled triangles and the special property involving the sides. We will define and use the theorem of Pythagoras to find the third unknown side of a right-angled triangle.

• Lesson 4 60 minutes with Katlego on Thursday, 31 Aug 2023, 17:00

We move on to quadrilaterals, starting with the properties of other two-dimensional shapes. In this first of two lessons, we focus on the following shapes: parallelogram, rectangle, square and rhombus.

• Lesson 5 60 minutes with Katlego on Tuesday, 5 Sep 2023, 17:00

In this second of two lessons about quadrilaterals, we focus on the properties of the trapezium and kite. We then learn how to apply the properties to answer questions that may have an algebraic and geometric touch.

## Congruency

Lesson 6 is all about the conditions that make two shapes congruent. First we take a look at important vocabulary, as well as the four ways in which we can prove congruency in triangles. Then we will take a look at other shapes and how they can be congruent as well.

• Lesson 7 60 minutes with Katlego on Tuesday, 12 Sep 2023, 17:00

## Similarity

In this lesson, we look at similarity and how to prove it in all two-dimensional shapes.

• Lesson 8 60 minutes with Katlego on Thursday, 14 Sep 2023, 17:00

## Problem Solving

In our final lesson for this section, we take a look at some exam-type questions that you may come across, and learn strategies on how to solve complicated geometry exam questions, specifically ones that involve quadrilaterals.
