How to Find Orthocenter of a Triangle: CBSE Maths Exam Notes

Let us consider a triangle DEF, as shown in the figure below.

- DA, EB and CF are the perpendicular lines drawn from the three vertices D, E and F respectively. - O(x,y) is the orthocentre (intersection point) of the triangle DEF.

Step 1:

Steps to find orthocentre of a triangle:

Using the formula, find the slope of the triangle's sides:

Step 2:

The slope of the altitudes of a triangle will be perpendicular to the slope of the sides of the triangle.
