Geometry: Straight Lines and Triangles [Foundation]
In this course, we will start our mathematical journey into serious high school Geometry. We will look at all the reasons associated with straight lines and triangles. This section requires some problem solving and equation work and will set a great foundation for Grade 10 Geometry.
Lesson 1 60 minutes with Jennifer on Tuesday, 9 Aug 2022, 17:00
We go through rules and reasons taught in Grade 8, focusing on straight lines.
Lesson 2 60 minutes with Jennifer on Thursday, 11 Aug 2022, 17:00
We look at vertically opposite angles and the related questions that combine this new rule with the ones revised in the previous lesson.
Lesson 3 60 minutes with Jennifer on Tuesday, 16 Aug 2022, 17:00
We define the different types of triangles and look at the rule for the sum of angles in a triangle.
Lesson 4 60 minutes with Jennifer on Thursday, 18 Aug 2022, 17:00
We will learn to understand the base angles of isosceles triangles.
Lesson 5 60 minutes with Jennifer on Tuesday, 23 Aug 2022, 17:00
We will use this sneaky rule to find angles outside of triangles.
Lesson 6 60 minutes with Jennifer on Thursday, 25 Aug 2022, 17:00
In this final lesson we work on mixed questions, using all the rules we learnt in this course.
