What is a Triangle?

A triangle is a three-sided polygon with three angles. It is the simplest closed figure in geometry and forms the basis of many mathematical concepts. Triangles are classified based on their sides and angles.

Types of Triangles by Sides

1. Equilateral Triangle: All three sides are equal, and each angle measures .

2. Isosceles Triangle: Two sides are equal, and the angles opposite these sides are also equal.

3. Scalene Triangle: All three sides have different lengths, and all angles are different.

Types of Triangles by Angles

1. Acute Triangle: All angles are less than .

2. Right Triangle: One angle is exactly , with the side opposite this angle known as the hypotenuse.

3. Obtuse Triangle: One angle is greater than .

Properties of Triangles

1. Angle Sum Property:

   • The sum of the interior angles of a triangle is always 180^o.

   Example: If two angles are 60^o and 70^o, the third angle is: 50^o

2. Exterior Angle Property:

   • An exterior angle is equal to the sum of the two non-adjacent interior angles.

3. Pythagoras Theorem (For Right Triangles):

   • h² = p² + b². Here, p and b are the legs, and h is the hypotenuse.

4. Area of a Triangle:

   • ½ × b × h. For a triangle with base b and height h.

5. Perimeter:

   • The perimeter is the sum of the lengths of all sides:

How to Solve a Triangle

1. Find the Missing Angle

Use the angle sum property:

2. Find Side Lengths Using Pythagoras Theorem

For right triangles:

3. Apply Trigonometric Ratios

4. Heron’s Formula (For Area)

Area = √[s(s - a)(s - b)(s - c)]

where a, b, and c are sides of the triangle.

Example Problem Solved with the Triangle Calculator

Example 1: Finding the Missing Angle

A triangle has two angles measuring 50^o and 60^o. Find the third angle.

Solution: 

Let, third angle be x

∴ x + 50^o + 60^o = 180^o [Sum of angles of a triangle is 180^o]

Or, x = 180^o - 50^o - 60^o

Or, x = 70^o
