To find the area of different types of triangles, you can use special formulas based on what information you have. Here’s a simple guide:
General Triangle: To find the area, use this formula: [ A = \frac{1}{2} \times b \times h ] Here, ( b ) is the base of the triangle, and ( h ) is the height.
Right Triangle: For right triangles, the area is calculated like this: [ A = \frac{1}{2} \times a \times b ] In this case, ( a ) and ( b ) are the lengths of the two sides that make the right angle.
Equilateral Triangle: An equilateral triangle has all sides the same length. If the length of one side is ( s ), the area is: [ A = \frac{\sqrt{3}}{4} s^2 ]
Using Heron’s Formula: If you know all three sides of a triangle, called ( a ), ( b ), and ( c ), you need to first calculate something called the semi-perimeter, ( s ): [ s = \frac{a + b + c}{2} ] Once you have ( s ), you can find the area using: [ A = \sqrt{s(s-a)(s-b)(s-c)} ]
In short, depending on the type of triangle and what you know about it, you can use different formulas to find the area.
