📐 Trigonometry in a right triangle and the concept of the hypotenuse and legs.

🔺 Understanding the names and properties of the sides in a right triangle.

📏 Introducing the concepts of sine, cosine, and tangent in relation to a right triangle.

🔑 The sum of the internal angles in any triangle is always 180 degrees.

📏 The Pythagorean theorem states that the square of the hypotenuse in a right triangle is equal to the sum of the squares of the other two sides.

➗ Trigonometric ratios involve dividing different sides of a right triangle.

The video explains the trigonometric functions sine, cosine, and tangent in relation to a right triangle.

The key concept is the relationship between the angle and the sides of the triangle, specifically the opposite and adjacent sides.

The relative values of the opposite and adjacent sides depend on the angle being considered.

📐 Trigonometry is a branch of mathematics that deals with the relationships between the angles and sides of triangles.

📚 The three main trigonometric functions are sine, cosine, and tangent, which are used to calculate the ratios of the sides of a right triangle.

🧮 The Pythagorean theorem can be used to calculate the length of the missing side of a right triangle using the lengths of the other two sides.

📐 The video discusses trigonometric ratios (sine, cosine, tangent) in a right triangle.

⚡ The opposite, adjacent, and hypotenuse sides of the triangle are used to calculate the ratios.

📝 The trigonometric ratios of alpha and beta are demonstrated using specific values.

🔑 Understanding the trigonometric ratios (sine, cosine, tangent) is crucial in solving problems in trigonometry.

📐 The values of the opposite and adjacent sides of a right triangle depend on the angle being considered.

🔢 By applying the trigonometric ratios and using known side lengths, it is possible to calculate unknown side lengths.
