Geometry Final Review

Front

What is the angle of elevation?

Back

The angle of elevation is the angle formed by the horizontal line and the line of sight to an object above the horizontal line.

Front

How do you calculate the height of an object using the angle of elevation?

Back

Use the formula: height = distance * tan(angle of elevation).

Front

What is the formula for the sine function in a right triangle?

Back

sin(θ) = opposite side / hypotenuse.

Front

What is the formula for the cosine function in a right triangle?

Back

cos(θ) = adjacent side / hypotenuse.

Front

What is the formula for the tangent function in a right triangle?

Back

tan(θ) = opposite side / adjacent side.

Front

What does it mean to reflect a shape across the y-axis?

Back

To reflect a shape across the y-axis, you flip it over the y-axis, changing the sign of the x-coordinates of the points.

Front

What is a 90-degree clockwise rotation?

Back

A 90-degree clockwise rotation turns a shape around a point (usually the origin) in the direction of the clock hands.

Front

What is the Pythagorean theorem?

Back

In a right triangle, a² + b² = c², where c is the hypotenuse.

Front

How do you find the missing side of a right triangle?

Back

Use the Pythagorean theorem or trigonometric ratios (sine, cosine, tangent) depending on the information given.

Front

What is the relationship between the angles in a triangle?

Back

The sum of the interior angles in a triangle is always 180 degrees.
