Sine Cosine Tangent #shorts

The video tutorial covers the basics of right triangles, focusing on the Pythagorean theorem and the trigonometric functions sine, cosine, and tangent. It explains how these functions are used to compare the sides of a triangle, with sine comparing the opposite side to the hypotenuse, cosine comparing the adjacent side to the hypotenuse, and tangent comparing the opposite side to the adjacent side. The tutorial provides examples of calculating these ratios and emphasizes understanding the relationships between the sides of a triangle.

What is the Pythagorean theorem used for in right triangles?

• To measure the perimeter of the triangle

• To calculate the area of the triangle

• To determine the relationship between the sides

• To find the relationship between the angles

Which side of a right triangle is always the longest?

• The base

• The hypotenuse

• The adjacent side

• The opposite side

What does the sine function compare in a right triangle?

• Opposite side to adjacent side

• Opposite side to hypotenuse

• Adjacent side to hypotenuse

• Adjacent side to opposite side

If the cosine of an angle in a right triangle is 0.8, what does this mean?

• The adjacent side is 80% of the hypotenuse

• The adjacent side is 80% of the opposite side

• The opposite side is 80% of the hypotenuse

• The hypotenuse is 80% of the opposite side

What is the tangent of an angle in a right triangle?

• The ratio of the hypotenuse to the adjacent side

• The ratio of the hypotenuse to the opposite side

• The ratio of the adjacent side to the hypotenuse

• The ratio of the opposite side to the adjacent side
