Area of a Triangle, Given 3 Sides, Heron's Formula

This geometry video tutorial explains how to find the area of a triangle using multiple formulas. It explains how to find the area of a right triangle using the formula A=1/2bh. All you need is the base and the height of the triangle. This video contains an example of using the pythagorean theorem to find the missing side of a right triangle. In addition, this tutorial provides the formula to find the area of an equilateral triangle given all 3 sides. This lesson also provides the formula to find the area of a scalene triangle given SAS - two sides and an angle using sines / trigonometry. Finally, this video explains how to find the area of a triangle with all 3 sides (SSS) using heron's formula. As you can see, this video contains plenty of examples and practice problems.

[@sararamazani3105]

Great video! Thanks for sharing it 😊👍, But I have a question. When we have a traingle where two sides with different measurement and an included angle are given, we should use the formula (A=1/2×ab×sin C). Can we also use the pythagorean theorem to find the measure of the heigt, considering the the traingle has different side measurements? Or does the pythagorean theorem only apply to traingles with at lease two similar sides?

[@daviskidangath9740]

Thanks. If it is possible, make a ready reckoner app for finding out area of triangles by typing three sides of triangles. It will be useful when a lot of triangles have to be calculated. It will reduce arithmetic tasks. Pl. inform if already there is any one like this which will not harm the device. Thank U

A=3/4 S^2 is a new addition of getting area of a triangle. This means that 25 and root of 2 the area of a triangle of sides 9, 10 and 11 is equals to 3/4 * 15 ^2.

Aint that sine not sin?

[@msolec2000]

Yes, the name of the function is sine, but when you speak you can say "sin 30" and it will be understood. In the same manner, you can say "cos 30" or "tan 30" or even, moving away from trigonometry, "log 30", and it will cause no trouble.
