What is the angle of elevation?

The angle of elevation is the angle formed by the line of sight when looking up from a horizontal line to an object above.

What is the angle of depression?

The angle of depression is the angle formed by the line of sight when looking down from a horizontal line to an object below.

How do you calculate the distance to an object using angles?

Use trigonometric ratios: For example, if you know the angle of elevation and the height, use $$\text{distance} = \frac{\text{height}}{\text{tan}(\theta)}$$ .

What is the relationship between the sides of a 30-60-90 triangle?

In a 30-60-90 triangle, the lengths of the sides are in the ratio 1 : $$\frac{\text{sqrt}(3)}{2} : 2$$ .

What is the relationship between the sides of a 45-45-90 triangle?

In a 45-45-90 triangle, the lengths of the legs are equal, and the hypotenuse is $$\text{leg} \times \text{sqrt}(2)$$ .

How do you solve for an unknown side in a right triangle?
