Question

Match the special lines of a triangle given on the left with the name of their point of intersection.

• A. centroid
• B. incentre
• C. orthocentre

Answer 1

A line segment joining a vertex of a triangle to the mid-point of its opposite side is called a median of the triangle.
A perpendicular line segment from a vertex of a triangle to its opposite side is called an altitude of the triangle.
A line segment that bisects one of the vertex angles of a triangle is called an angle bisector.
In a triangle, the point of intersection of:
all the 3 medians - centroid.
all the 3 altitudes - orthocentre
all the 3 angle bisectors - incentre.
