Using the formula for area of a triangle equal to , drawing and labelling its sides, angles, and height h, then using triangle trigonometry and substitution, we can derive the formulae , where

We can adapt this formula using the trigonometric ratio sin(θ)= O H sin(θ) = H O to work out the area of a triangle when we do not know its vertical height. The formula we get is: Area of

The area of a triangle can be expressed using the lengths of two sides and the sine of the included angle. AreaΔ = ½ ab sin C. You may see this referred to as the SAS formula for the area of a triangle. With this new formula, we no longer

This app was great and really helped me with hard concepts and improved my overall grade. This app works very well and it has helped improve my mathematical grades a lot, 10/10 recommend this app for all phases of school and life.

I found my book and now I have every solution of every exercise in my book, hats off to apps which are useful for us in such a way that we can study easily, this app is amazing! It works amazingly with the regular version and I definitely would recommend to get the plus version! This app has helped me so much.

Ya know, sometimes the smart kid is tired of being smart :)) So i downloaded this, (without caring what the teachers say about "cheating" hehe) i've never seen it being wrong, it's always correct, the premium version shows you step by step how to solve the problem and tells what formula it used.
