Right Triangle

Finding angles:

• α = arcsin(a / h)
• α = arccos(b / h)
• α = arctan(a / b)
• α = 90 - β

• β = arcsin(b / h)
• β = arccos(a / h)
• β = arctan(b / a)
• β = 90 - α

Finding sides:

• a = h x sin(α)
• a = h x cos(β)
• a = b x tan(α)
• a = b / tan(β)
• a = √h² - b²

• b = h x sin(β)
• b = h x cos(α)
• b = a x tan(β)
• b = a / tan(α)
• b = √h² - a²

• h = a / sin(α)
• h = b / cos(α)
• h = a / cos(β)
• h = b / sin(β)
• h = √a² + b²
