Formulas for a Triangle

perimeter- a + b + c (add all sides)
semiperimeter- a + b + c ÷ 2 (add all sides the divide by 2)
area- base • height ÷ 2 (multiply base by heighth divide by 2)
base- 2 • area ÷ height (2 by area divide by heighth)
height- 2 • area ÷ base (2 by area divide by base)





are these the correct formulas of a triangle?
