Question

How to find the altitude of a right angled triangle , equilateral triangle, isosceles triangle,and scalene triangle ??

Answer 1

Dear student,

For a right angled triangle, you can use the Pythagorus theorem to find its altitude given the other two sides.

Altitude of the equilateral triangle is $\frac{\sqrt{3}}{2}a$
Where a is the side of the equilateral triangle.

Height of an isosceles triangle is $\sqrt{a^2-\frac{b^2}{4}}$
Where a is the side and b is the base.

Height of the scalene triangle can be calculated as $2\frac{A}{b}$
Where A is the area of the triangle and b is the base of the triangle.
