This interactive applet enables students to visualise and subsequently deduce the formula to find the area of a circle. By Ooi Soo Huat, SMK Che T…
Students are expected to have already known how to find the circumference of a circle
Rectangles in the {Perimeter, Area} plane
What have you learned from this applet?
An interactive file for students to discover the relationship between slopes of perpendicular lines.
Lines a and b have been constructed to be perpendicular.
Circles – AS
The baseline and are tangents to the circle and have gradient . a) Find the points
Multiplying Fractions
Click the „Drag“ button after the fractions have been entered.

I wanted you to be able to set the number of petals, design the petal, and have a
Locus (B)
Use the GeoGebra tools to construct the path (or paths) ALL of the points that have
Angle Bisectors and Altitudes Notes2
What you have just constructed is called an altitude.
Converting Cartesian graphs into polar graphs
Press Show negative r to see where negative r values are plotted once you have plotted
Angles Inside Circle
Once you think you have a formula that works.
