Now, it's the time when things get complicated. We used the same equations as in the previous example:Īrea = Length × (a + b + c) + (2 × Base area)Īrea = Length × Base perimeter + (2 × Base area) ▲ 2 sides + angle between
Where a, b, c are the sides of a triangular base This can be calculated using the Heron's formula:īase area = ¼ × √ We're giving you over 15 units to choose from! Remember to always choose the unit given in the query and don't be afraid to mix them our calculator allows that as well!Īs in the previous example, we first need to know the base area. If you're given 2 angles and only one side between them If they give you two sides and an angle between them
If they gave you all three sides of a triangle – you're the lucky one! You can input any two given sides of the triangle - be careful and check which ones of them touch the right angle (a, b) and which one doesn't (c). You need to pick the ◣ right triangle option (this option serves as the surface area of a right triangular prism calculator).
If only two sides of a triangle are given, it usually means that your triangular face is a right triangle (a triangle that has a right angle = 90° between two of its sides). Find all the information regarding the triangular face that is present in your query:
