Construction of Triangles(ASA)- Activity 4

Process (How to do the activity)
‘Play’ the construction protocol navigator to understand the construction, after students have constructed on their own Draw the altitude from vertex A to segment BC. Label the intersection as D
 * 1) with	following measures  - BC =  12 cms, ∡B	= 60, ∡C = 60, (BC as the base)
 * 1) What kind of triangle is it?
 * 2) What kind of triangle is it - by sides?
 * 3) What kind of triangle is it - by angles?
 * 4) Can this triangle be an obtuse angled triangle?

Measure its length. Measure ∡ADB and ∡ADC.

Measure the area of the triangle ABC
