Introduction to learn geometry fast and free:
This article is going to help us on learn geometry fast and free. we can learn geometry in the very fast manner and absolutely free at online. Geometry is about shapes and its angles, finding area's, volume's. .There two kinds of geometry, 1. Plane geometry ,2. Solid geometry. we can learn these two basic geometry for free as well as very fast manner if we go for online tutoring. let we see some problems for learn geometry fast and free.

Fast and free geometry - problem) find the unknown angle for the given diagram.

Solution:
Here we need to find the value of x
The sum of interior angle of a triangle is = 180^o
A + B+C = 180
Here A = 90^o and B = 40^o
Apply these values in the above formula ,we get
90+40 +C = 180
130 + C =180
Add -130 on both sides, 
130-130+C = 180-130
C = 180 - 130
C = 50
The angle of C value is 50^o.
