=== Prerequisites/Instructions, prior preparations, if any ===
Angles, angle bisectors , concurrent lines and triangles should have been covered.
===Materials/ Resources needed===
===Materials/ Resources needed===
Digital resources: Laptop, projector and a pointer.
Geogebra file: This geogebra file was done by ITfC-Edu-Team.
What are the student follow-up activities/ questions you can give?
===Process (How to do the activity)===
#The teacher can use this geogebra file and ask the questions listed below.
*Developmental Questions;
#What type of triangle is this ? Why ?
#Identify the three angles.
#What is an angle bisector ?
#Identify the point of concurrence of angle bisectors ?
#This point, called incentre of the triangle does its position change with the type of triangle ?
#Identify the circle. What is its radius ? What can this radius be called ?
#What is this circle called ?
*Evaluation:
#What is incentre, inradius and incircle ?
*Question Corner:
#What do you think would be the practical applications of the incentre and incircle ?
