# '''with	following measures  - BC =  12 cms, ∡B	= 60, ∡C = 60, (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?
# Can this triangle be an obtuse angled triangle?
Draw the altitude from vertex A to segment BC. Label the intersection as D

Measure its length. Measure ∡ADB and ∡ADC.
