**Triangles**

**Ā**

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 āABC instead of

writing āTriangle ABCā.

In āABC, how many sides and how

many angles are there?

The three sides of the triangle are

AB, BC and CA. The three angles are

ā BAC, ā BCA and ā 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

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

Ā Ā Do This

Ā Ā AB and BA denote the same line segment.

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

Ā Ā indefinitely; it is denoted by AB

Ā Ā 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 thisĀ Ā Ā Ā 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.

Ā Ā Ā An angle leads to three divisions of a region:

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

12. A triangle is a three-sided polygon.
