Perpendicular Bisector of Chord
- Norhuda Mohd Sadekan
Sliders for changing the following: 1. Radius of the circle, Blue dots for changing the lengths of the chords: 1. BC. Pre-requisite knowledge and terms: Perpendicular bisector, Chord Task: Explore and manipulate the applet. Make a conjecture on the property of the chord and record it in your class wall. Questions to guide in Investigation 1: 1a) For the various lengths of the chord BC, what can you say about the lengths of BD and DC? Why do they behave so? 1b) Where is the centre of the circle located? Is it true for various lengths of BC? 1c) What is your conjecture of the property of the chord here? Write it on your class wall.
