Front

What is the cosine ratio in a right triangle?

Back

The cosine ratio is defined as the ratio of the length of the adjacent side to the length of the hypotenuse.

Front

How do you find the length of a side in a right triangle using trigonometric ratios?

Back

You can use the sine, cosine, or tangent ratios depending on the known angles and sides.

Front

What is the formula for the area of a sector?

Back

Area = (θ/360) * π * r², where θ is the angle in degrees and r is the radius.

Front

What is the tangent ratio in a right triangle?

Back

The tangent ratio is defined as the ratio of the length of the opposite side to the length of the adjacent side.

Front

How do you determine the measure of an angle in a triangle?

Back

You can use the properties of triangles, such as the sum of angles in a triangle equals 180 degrees.

Front

What is the sine ratio in a right triangle?

Back

The sine ratio is defined as the ratio of the length of the opposite side to the length of the hypotenuse.

Front

How do you round a number to one decimal place?

Back

Look at the second decimal place; if it's 5 or more, round up the first decimal place.

Front

What is the relationship between the sides and angles in a right triangle?

Back

The sides opposite larger angles are longer, and the sides opposite smaller angles are shorter.

Front

What is the Pythagorean theorem?

Back

In a right triangle, a² + b² = c², where c is the hypotenuse and a and b are the other two sides.

Front

How do you find the measure of an unknown side using the cosine ratio?

Back

Use the formula: cos(θ) = adjacent/hypotenuse, rearranging to find the unknown side.
