Construction of Triangles(SSS)- Activity 2

Materials/ Resources needed
Construction of a triangle with 3 sides.ggb

Process (How to do the activity)
Draw the altitude from vertex A to segment BC. Label the intersection as D
 * 1) 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
 * 2) What		kind of triangle is it?
 * 3) What			kind			of			triangle is it - by sides?
 * 4) What			kind of triangle is it - by angles?
 * 5) Would		it be possible to draw a triangle, if AB was changed to 9 cms? Why
 * 6) Would		it be possible to draw a triangle, if AB was changed to 8 cms? Why

Measure its length. Measure ∡ADB and ∡ADC.

Measure the area of the triangle ABC
