Question

In isolation (triangle) ABC, AB=AC=8cm and BC=6cm. If the length of altitude on base is 5cm. find the length of altitude on equal side of triangle.

Answer 1

Answer:

13 cm. applying Pythagoras Theorem, we get

AB = sqrt((AC)^2 + (BC)^2)

or, AB = sqrt(5^2 + 12^2)

or, AB = sqrt(25+144)

or, AB = sqrt(169)

so, AB = 13 cm. :)
