Construction of Triangles(ASA)- Activity 4

Materials/ Resources needed
Construction of triangle with 1 side and two angles.ggb

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
