Question

Determine the length of the altitude AD of an isosceles triangle abc in which ab=ac= 2a CM and bc=a CM

Answer 1

Answer:

In isosceles ∆ ABC, we have: 

AB = AC = 2a units and BC = a units 

Let AD be the altitude drawn from A that meets BC at D. 

Then, D is the midpoint of BC. 

BD = BC = a/2 units  Applying Pythagoras theorem in right-angled ∆ABD, we have:
