Good days Class! Today we will discuss about Trigonometric.
Trigonometry starts with the ratio of two sides of a right angled triangle. There are three basic trigonometric ratios in the beginning.A right angled triangle is one with one 90 degree angle and two angle less than 90 degree.
The teacher discusses the key concept of the lesson.
An introduction to Trigonometry
Let's talk about a right angled triangle and get familiar with it so that we can start trigonometry

Trigonometry start with the ratio of two sides of a right angled triangle. There are three basic trigonometric ratios in the beginningA right angled triangle is one with one 90 degree angle and other two angles less than 90 degree.
Cosine Ratio When we divide the adjacent by the hypotenuse, the ratio is known as cone of the angle θ

Sine Ratio: When we divide the opposite by the hypothenuse the ratio is known as sine of the angle θ
Very Good students! You're all correct. Now I will give more example after that, let's have a short quiz.
Tangent Ratio: When we divide the opposite side by the adjacent side, the ratio is known as tangent of the angle θ
The teacher administered a short quiz after providing examples.
