SUBJECT MATHEMATICS

. 1) The altitude or height 2) The perpendicular bisector 3) The median 4) The angle bisector

THE ALTITUDE OR HEIGHT In a triangle, a segment drawn through a vertex perpendicular to the opposite side is called the altitude or height of the triangle. A seg. AD is the altitude B D C

THE THREE ALTITUDE OF ANY TRIANGLE ARE CONCURRENT. . A H B K I G C

The perpendicular bisector A perpendicular line drawn through the midpoint of the side of a triangle is called the perpendicular bisector of that side A l D B C

THE PERPENDICULAR BISECTOR OF THE THREE SIDE OF A TRIANGLE ARE CONCURANT D is point of concurrence. A H B D G I C

The median The line segment joining the vertex of a triangle to the midpoint of it’s opposite side is called a median of the triangle. A B H C

THE THREE MEDIANS OF A TRIANGLE ARE CONCURRENT. A H B D I G D IS POINT OF CONCURRENT C

The Angle bisector The line segment bisect the angle of a triangle is called angle bisector of a triangle A . B C

The three angle bisector of a triangle are concurrent D is point of concurrence A D B C

EXERCISE 1) Draw ∆XYZ Draw it’s three Altitude 2) Draw ∆ PQR Draw it’s three median 3) Draw ∆ABC Draw it’s three perpendicular bisector 4) Draw ∆LMN bisector Draw it’s three angle
