In this tutorial we show you how to name the sides of a right-angled triangle in preparation for using trigonometry to find lengths and angles in right-angled triangles

In this tutorial I show you how to find the length of a side by using trigonometry when the missing side is in the top of the trigonometry ratio fraction.
this is done if you are given the opposite angle and the two other sides.

00:03 CBSE class 10 maths NCERT Solutions Trigonometry Ex 8.1 q5. Given sec theta = 13/12 calculate all other trigonometric ratios.
00:30 Finding sides of sides of right triangle
00:48 naming the sides
00:51 Use Trigonometric Ratio
secant of angle theta = hypotenuse / side adjacent to angle theta
01:27 The values of the trigonometric ratios of an angle do not vary with the lengths of the sides of the triangle, if the angle remains the same.
01:41 Pythagoras Theorem
In a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
02:37 Defination of Trigonometric Ratio
sine of angle theta = side opposite to angle theta / hypotenuse
sin is equal to opposite over hypotenuse.
Remember as ' SOH '
02:08 cosine of angle theta = side adjacent to angle theta / hypotenuse
Remember as ' CAH ' Cosine equals Adjacent over Hypotenus.
03:20 Tangent of angle theta = side opposite to angle theta / side adjacent to angle theta.
Remeber as ' TAO '. Tan is adjacent over
03:48 RECIPRACAL IDENTITY
04:46 CBSE class 10 maths NCERT Solutions Trigonometry Ex 8.1 q1. In triangle ABC, right-angled at B, AB = 24 cm, BC = 7 cm. Determine
(i) sin A, cos A (ii) sin C, cos C
05:08 Finding sides of right triangle.
06:29 Pythagoras Theorem
06:20 Trigonometric Ratio Defination
sine of angle theta = side opposite to angle theta / hypotenuse
sin is equal to opposite over hypotenuse.
Remember as ' SOH '
06:55 cosine of angle theta = side adjacent to angle theta / hypotenuse
Remember as ' CAH ' Cosine equals Adjacent over Hypotenus.
08:40 4. Given 15 cot A = 8, find sin A and sec A.
09:11 Naming the sides
09:43 cotangent of angle theta = side adjacent to angle theta / side opposite to angle theta
10:23 Pythagoras Theorem
11:03 Trigonometric Ratio Defination
sine of angle theta = side opposite to angle theta / hypotenuse
sin is equal to opposite over hypotenuse. Remember as ' SOH '
11:42 Trigonometric Ratio Defination 'secant'
secant of angle theta = hypotenuse / side adjacent to angle theta
