angles

How do you find the measure of an unknown angle?

• By using the properties of angles, such as complementary and supplementary angles, or applying trigonometric ratios.

• By measuring the angle with a protractor only.

• By estimating the angle based on surrounding angles.

• By using a compass to draw the angle.

What is the cosine of an angle?

• The cosine of an angle is the ratio of the length of the opposite side to the length of the hypotenuse.

• The cosine of an angle is the ratio of the length of the adjacent side to the length of the hypotenuse.

• The cosine of an angle is the ratio of the length of the hypotenuse to the length of the adjacent side.

• The cosine of an angle is the ratio of the length of the adjacent side to the length of the opposite side.

What is an angle?

• An angle is formed by two rays (sides) that share a common endpoint (vertex).

• An angle is a measure of the distance between two points.

• An angle is a straight line that connects two points.

• An angle is a figure formed by three intersecting lines.

What is the sine of an angle?

• The sine of an angle is the ratio of the length of the adjacent side to the length of the hypotenuse.

• The sine of an angle is the ratio of the length of the opposite side to the length of the hypotenuse.

• The sine of an angle is the ratio of the length of the hypotenuse to the length of the opposite side.

• The sine of an angle is the ratio of the length of the opposite side to the length of the adjacent side.

What is the tangent of an angle?

• The tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side.

• The tangent of an angle is the sum of the lengths of the opposite and adjacent sides.

• The tangent of an angle is the product of the lengths of the opposite and adjacent sides.

• The tangent of an angle is the difference between the lengths of the opposite and adjacent sides.
