**Triangles**

A triangle is a three-sided polygon.

In fact, it is the polygon with the least

a number of sides.

Look at the triangle in the diagram

We write ∆ABC instead of

writing “Triangle ABC”.

In ∆ABC, how many sides and how

many angles are there?

The three sides of the triangle are

AB, BC and CA. The three angles are

∠BAC, ∠BCA and ∠ABC. The points

AB and C are called the vertices of

the triangle.

Being a polygon, a triangle has an

exterior and an interior

**What have we discussed?**

1. A point determines a location. It is usually denoted by a capital letter.

2. A-line segment corresponds to the shortest distance between two points. The

the line segment joining points A and B is denoted by AB.

Do This

AB and BA denote the same line segment.

3. A-line is obtained when a line segment like AB is extended on both sides

indefinitely; it is denoted by AB

or sometimes by a single small letter like l.

4. Two distinct lines meeting at a point are called intersecting lines.

5. Two lines in a plane are said to be parallel if they do not meet.

6. A ray is a portion of line starting at a point and going in one direction endlessly.

7. Any drawing (straight or non-straight) done without lifting the pencil may be called a curve. In this sense, a line is also a curve.

8. A simple curve is one that does not cross itself.

9. A curve is said to be closed if its ends are joined; otherwise it is said to be open.

10. A polygon is a simple closed curve made up of line segments. Here,

(i) The line segments are the sides of the polygon.

(ii) Any two sides with a common end point are adjacent sides.

(iii) The meeting point of a pair of sides is called a vertex.

(iv) The end points of the same side are adjacent vertices.

(v) The join of any two non-adjacent vertices is a diagonal.

11. An angle is made up of two rays starting from a common end point.

An angle leads to three divisions of a region:

On the angle, the interior of the angle and the exterior of the angle.

12. A triangle is a three-sided polygon.
