**In this post, we will discuss all the properties related to orthocenter of a triangle which will help us solve geometric questions in SSC CGL Exams.**

**What is Orthocenter? Many aspirants who attempt SSC Exams have this question and they often fail to understand the concept and skip geometric questions that are asked on orthocenter of a triangle. In this post, we will discuss all the properties of orthocenter of a triangle which will help you solve geometric questions and hence help you crack SSC Exams easily.**

In our previous post, we have discussed the centroid of a triangle. In this post, we will discuss another centre of a triangle named orthocenter of a triangle.

Before moving further let's understand the most important term related to orthocentre of a triangle - Altitude.

###
**What is an Altitude of a triangle? **

Altitude of a triangle is a perpendicular which is drawn from the vertex of a triangle to the opposite side of a triangle. **AD is the Altitude**

In a triangle, there are only three altitudes that can be drawn.

**AD, CF, and BE are the Altitudes of the triangle given below.**

###
**What is orthocenter of a triangle? **

Orthocenter of a triangle is the point of intersection where all the three altitudes of a triangle intersect.Orthocenter is denoted by the letter "H."

###
**Position of the Orthocenter of a Triangle for different types of triangles:**

Based on the type of a triangle, the position of the orthocenter changes.**1. Acute Angled Triangle:**In an acute angled triangle, the orthocenter of the triangle lies inside the triangle.

**2. Obtuse Angled Triangle:**In an obtuse angled triangle, the orthocenter of the triangle lies outside the triangle.

**3. Right Angled Triangle:**In a right angled triangle, the orthocenter of the triangle lies on the vertex of the triangle.

####
**The angle made by any side with the orthocenter of a triangle and the vertical angles are supplementary**

1. Angle BHC + Angle A = 180 degrees

2. Angle AHC + Angle B = 180 degrees

3. Angle AHB + Angle C = 180 degrees

Hope it's now easier for you to attempt questions that are based on the orthocentre of a triangle.
