[[:File:1. Construction of a triangle with 3 sides.ggb|Construction of a triangle with 3 sides.ggb]]

=== Process (How to do the activity) ===
# Draw	 a triangle with following measures  - BC =  5	cms, AC = 3	cms, AB = 7	cms (BC as the base).  ‘Play’	the construction protocol navigator to understand the construction,	after	students have constructed on their own
## What		kind of triangle is it?
### What			kind			of			triangle is it - by sides?
### What			kind of triangle is it - by angles?
## Would		it be possible to draw a triangle, if AB was changed to 9 cms? Why
## Would		it be possible to draw a triangle, if AB was changed to 8 cms? Why
Draw the altitude from vertex A to segment BC. Label the intersection as D

Measure its length. Measure ∡ADB and ∡ADC. 

Measure the area of the triangle ABC
