(1) Basic Geometry
This morning, we conclusion "Basic Geometry" with discussions on Assignment 1 & Assignment 2, wit the online quizzes.
Assignment 1: Please review the angle properties you have in the handout.
Assignment 2: Complete the worksheet
Hand-in Assignments 1 & 2 on MONDAY (28 August 2017)
On Monday, you will be given a short quiz on Angle Properties (5 min)
You were given the set of hand-outs for the Mensuration (Area and Perimeter of Planes).
Go through the handouts before the lesson.
You may watch the video clips in the post to help you understand how the formulae (area of parallelogram and trapezium) are derived, based on what you already know.
You may take your time to read/ watch how the problems are solved. Complete this before Term 4 starts.
Watch the following examples. Each comes with a question and the explanation on how to solve the problem.
1. Pause the question. Read the diagram carefully and think what formula would help you to solve for the unknown.
2. Think how you would solve the problem - you may need to write down an equation in order to solve for the unknown.
3. Next, continue to watch the clip and listen to the explanation. Is this similar to what you have thought of? Look out for the presentation of the working.
At any one time, only one angle property to be cited
Lines may be extended or additional lines may be added, if necessary
Other angles (that are not labelled) can be labelled you need to make reference to them along the way (as part of the working).
You may label the angles and indicate the angle properties in the diagram. However, this must be clearly written.
However, you must not combine steps when presenting your working!
(although some of you process the steps very quickly)
When presenting your working in writing:
You must not cite more than one angle property for a single step.
You need to break down the steps, write the working clearly with any relevant angle property, if applicable.
