Objective: To learn on different properties in triangle
Subtopics to be covered:
- Altitude, Median of a triangle
- Perpendicular bisector of sides of triangle
- Angle bisectors of angles of triangle
Learning Outcome:
- Students can find out which is an altitute, median, bisector in a triangle based on given information
- Students can identify from the property stated what is asked about the triangle

1. Can a median of a side of triangle be out of the triangle ? Try and see.
2. Draw one equilateral triangle, one isosceles triangle, one scalene triangle. Find their altitudes and means. What is common about them?
