In this video we will discuss the theorems and some useful properties perpendicular bisectors and
orthocentre of a triangle.
The point of intersection of the three altitude of the triangle is called the orthocentre.
Altitude : The perpendicular drawn from a vertex to opposite side of a triangle.
Properties:-
In equilateral triangle all the three altitudes are equal in length.
In equilateral triangle perpendicular and median are same line segment.
In Isosceles triangle two perpendicular drawn from equal angles to equal sides are equal and perpendicular drawn from
unequal angle to unequal side is also median and also angle bisector.
In scalene triangle all the three perpendicular are unequal.
In acute angle triangle all the three perpendicular lie inside of triangle.
