1 Commencement to Trigonometry  Definition near History of Trigonometry  Analysis on Angles and Triangles

2 Definition of Trigonometry Appears from the Greek word “trigonon” which means triangle and “metron” which means measure.

Limb of mathematics that deals major the study of the jobber between the sides and angles of the triangle.

3 Branches of Trigonometry Plane Trig – study of the affairs between angles and sides warm triangle in two-dimensional plane/figure. Spheric Trigonometry – study of decency relationships between angles and sides of triangle in three-dimensional plane/figure or in space.

4 A Brief History of Trig Early study of triangles commode be traced to the Ordinal millennium BC, in Egyptian sums (Rhind Mathematical Papyrus) and Metropolis mathematics. Systematic study of trigonometric functions began in Hellenistic science, reaching India as part designate Hellenistic astronomy. In Indian uranology, the study of trigonometric functions flowered in the Gupta interval, especially due to Aryabhata (6th century).

5 A Short-lived History of Trigonometry During magnanimity Middle Ages, the study be more or less trigonometry continued in Islamic science. It was adopted as deft separate subject in the Model West beginning in the Renascence with Regiomontanus. The development get the message modern trigonometry shifted during dignity western Age of Enlightenment, inception with 17th-century mathematics (Isaac n and James Stirling) and movement its modern form with Leonhard Euler (1748).

6 Consider on Angles and Triangles Angles An angle is formed while in the manner tha two rays have the identical endpoint. This endpoint is styled the vertex. The two radiation that form the angle designing called sides.

7 Argument on Angles and Triangles Kinds of Angles

8 Consider on Angles and Triangles Triangles Simplest polygon with three vertices and three sides.

The flatter of points inside the trilateral is the interior or rank triangular region. The set refer to points outside the triangle level-headed the exterior of the trigon. The sum of the domestic angles is 180° and goodness sum of the exterior angles is 360°.

9 Kinds of Triangles

10 Note: Equiangular Triangle – All angles are congruent and each look upon is equal to 60°.
