A straight line drawn through the mid-point of one side and parallel to another side of a triangle bisects the third side..Introduction
We are familiar with plane figures bounded by straight line segments as sides. They are known as Polygons . Polygon is a word of Greek origin. It means figure with many angles implying many sides. Squares, rectangles and other four-sided g..
Triangle
A three sided closed figure is called a triangle. Here side means a line segmen..
Summary
Midpoint Theorem The straight line joining the mid-points of two sides of a triangle is parallel to and equal to half the third side. Converse of mid point theorem - The straight line drawn through the mid point of one side of a triangle, para..

Median
Recall a line segment joining the vertex to the mid-point of the opposite side of a triangle. In D ABC, AD is the line segment drawn from A to BC (opposite side of A). AD is a median of a triangle. "The line segment jointing a vertex of a triangle to the ..

Question: Which of the following statements are true and which are false? Give reasons for your answers. i) Only one line can pass through a single point. ii) There are infinite number of lines which pass through two distinct points. iii) A terminated line can be ..
Question 8
Question: Find the number of diagonals in a polygon of n sides. Answer: In a polygon, no three points are collinear. To draw a line, we require two distinct points. The polygon of n sides has n distinct points. Number of diagonals that can be drawn..
