Question

does an altitude bisects the opposite side?

Answer 1

An altitude from a vertex bisects the opposite base if and only if the two sides emerging from that particular vertex are equal(not necessary in a right angle triangle).Therefore, you need to specify this condition before assuming that the altitude cuts the opposite base in half.

Answer 2

The altitude drawn from intersection of equal

sides of a isoceles triangle will biect the

opposite side.

The altitude drawn from any vertex

of an equilateral triangle will biect the

opposite side.
