the tuird propertie of a triangle

poor formula's

It is better to set them up like this...

Let's say we have a triangle and one angle a =63, angle b=90, and angle c=?? .

You'd set it up like this...

c = a + b - 180

assuming that all triangles have 180 degree we must deduct 180 from "a" and "b"

c = 63 + 90 - 180

c = 153 - 180

c = 27

.: When deducting 180 from 2 angles it will give you the last angle which in this case was 27.
