[intro]
Calculating the properties of a triangle depends on what information you already have. Here’s a general guide:
[verse]
To calculate the angles of a triangle:
The sum of the internal angles in any triangle is always ( 180^\circ ) or ( \pi ) radians.
If you have a right triangle, one angle is ( 90^\circ ), and you can find the other angles if you know at least one other angle or side.
For non-right triangles, if you know two angles, you can find the third one by subtracting the sum of the known angles from ( 180^\circ ).

Where is the triangle?
Have you seen it today?
There is the triangle.
Great.
[verse2]
To calculate the area of a triangle:
For any triangle with base ( b ) and height ( h ), the area ( A ) is given by:A=21×b×h
If you know all three sides, say ( a ), ( b ), and ( c ), you can use Heron’s formula:A=s(s−a)(s−b)(s−c)
where ( s ) is the semi-perimeter of the triangle:s=2a+b+c
