What is Euclidean geometry?
It is an axiom system about points and Lines.
Five postulates of euclidean geometry are followed as;
1. To draw a straight line from any point to any other point. It means we can draw a straight line between any two pints.
2.To extend the continuous line in a straight line.
3. A circle can be drawn with any radius and center.
4. All right angles are equal to one another.
5. Parallel line postulate: If a straight line is falling on two straight lines make the interior angles on the same side less than the sum of two right angles, and the two straight lines.
