The area $A$ of a triangle can be calculated using the following formula:

$A = \frac{1}{2} \times \text{base} \times \text{height}$

Where:

• Base is the length of the triangle's base.
• Height is the perpendicular distance from the base to the opposite vertex.

1. How do you find the height of a triangle if only the sides are known?
2. What is the formula for the area of a triangle using Heron's formula?
3. How can the area of a right triangle be calculated differently?
4. How do you calculate the area of a triangle using its vertices' coordinates?

Tip: Remember, the base and height must be perpendicular to each other for this formula to work.
