Review - Right Triangle Trig.

Front

What is a right triangle?

Back

A right triangle is a triangle that has one angle measuring 90 degrees.

Front

What is the hypotenuse of a right triangle?

Back

The hypotenuse is the side opposite the right angle and is the longest side of the triangle.

Front

What are the two legs of a right triangle?

Back

The two legs are the sides that form the right angle.

Front

What is the Pythagorean theorem?

Back

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b): a² + b² = c².

Front

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

Back

You can use sine, cosine, or tangent ratios based on the angle and the sides involved.

Front

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

Back

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

Front

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

Back

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

Front

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

Back

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

Front

How do you calculate the angle of elevation?

Back

The angle of elevation is calculated using the inverse trigonometric functions based on the lengths of the sides.

Front

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

Back

The sum of the angles in any triangle is 180 degrees, and in a right triangle, the two non-right angles must sum to 90 degrees.
