Depends on what information you have and what you require.
If you have all three sides, there are different formulae to find the perimeter, angles and area.
If you have two sides and an angle (depending on the angle) you have formulae for the remaining side and then perimeter and area.
If you have a side and two angles there are formulae to find the missing sides and then perimeter and area.
There are other possibilities: you have the altitude and require the area; etc.
