| + | ===Objectives=== |
| + | To understand longest chord passes through the centre and it is the diameter |
| + | ===Estimated Time=== |
| + | 30 minutes |
| | | |
| + | ===Prerequisites/Instructions, prior preparations, if any=== |
| + | Prior knowledge of point, lines, angles, polygons |
| + | |
| + | ===Materials/ Resources needed=== |
| + | * Digital : Computer, geogebra application, projector. |
| + | * Non digital : Worksheet and pencil, compass, strings |
| + | * Geogebra files : Diameter is longest chord.ggb |
| + | |
| + | ===Process (How to do the activity)=== |
| + | Use the geogebra file to show how diameter is the longest chord. |
| + | |
| + | Move the points on the circle to show the changes in the triangle. |
| + | |
| + | What is the condition with respect to sides for formation of a triangle. Sum of two sides is larger than the third side. |
| + | |
| + | Compare the chord length with sum of two radii. When is the triangle reduced to a line segment. |
| + | |
| + | What can you conclude about the chord? When is it the largest? |
