Circle Theorems
Circles and Angles 1
Compare the angle at the centre to the angle on the circle. Move the points and become familiar with different versions of the diagram.
|
Circles and Angles 2
Compare the angle at the centre to the angle on the circle (obtuse and reflex angles). Move the points and become familiar with different versions of the diagram.
|
Circle Theorems - angles on the same arc
Investigate angles on the same arc. Move the points - what do you notice?
|
Angle in a Semi-circle 1
Move point A or D. What do you notice about the angles?
|
Angle in a Semi-circle 2
Angle in a semi-circle -proof.
|
Circle theorems - Cyclic Quadrilaterals
Move point A or C. What do you notice about the angles?
Move point B or D. What do you notice? Can you explain these results?
|
Circle theorems - Cyclic quadrilaterals
Look at the angles on each arc separately.
Look at both at the same time and move the points.
What do you notice?
|
Cyclic Quadrilateral 3
This shows how both pairs of opposite angles in a cyclic quadrilateral sum to 180°

Function Or Not?
Recall the following definitions:
A relation is a correspondence between 2 sets.
Algebraically, you can think of a relation as a set of ordered pairs (x,y).
Once special type of relation is called a FUNCTION.
Every function is a relation, but not every relation is a function.
A function is a relation for which each and every input gets mapped to ONE and ONLY ONE output.
The following applets help further illustrate this concept for functions represented graphically.
This relation is NOT A FUNCTION. Slide to see why.
