Geometry

Geometry is the branch of mathematics which deals with the measurements of angles and its properties. It deals with shapes, sizes and constructions of various geometric figures. We usually learn lot of theorems and corollary of which is being used in problems for solving different kinds of problems in circles, triangles and other application.

Geometry Formulas

More or less we deductive logic in geometry. Few formulas which can be put are

1. Sum of interior angles = Exterior angle.

2. Area of the triangle = √s(s-a)(s-b)(s-c).

3. Sum of the angles of a triangle are A + B + C = 180.

4. Sum of complementary angles = 90.

5. Sum of supplementary angles = 180.

Geometry Problems

Below you could see geometry problems

Solved Examples

Question 1: The two sides of a triangle are 30 and 45 degree respectively.Find the other side of the triangle.
Solution:
We knows that the sum of the 3 sides of the triangle is given by 180 .

So 30 + 45 + x  = 180

 x = 180 - 75

x = 105


Question 2: Find the complement of 46 degree
Solution:
The complement of 46 is 180 - 46 = 44 degree.
