right triangle

The following trigonometric formula is used to find the triangle's area:

A =  --- (1)

Where A = Area

b = Base

h = Height

If the base and the height of a triangle is given, you can use equation (1) to find the area of a triangle.

Note: Height is actually the perpendicular line to the base.

Answer:

we can find the area of any triangle using trignometric area formula

Step-by-step explanation:

Let A,B,C be three vertices of a triangle.  

then the area of traingle could be given as Area=[tex]\frac{1}{2}[/tex]×a×h

=[tex]\frac{1}{2}[/tex]×a×b×SinC

as SinC=[tex]\frac{h}{b}[/tex]

hence The area of a triangle could be expressed using the length of the two sides and the sine of the included angle.

this is referred to as SAS formula for the are a of a triangle.
