Euclid’s postulates chapter 5 can study by students of class 9. These definitiona and formulas of Class 9 Maths Chapter 5: Introduction to Euclid’s Geometry is developed and witten by our expert teachers. Maths formulas. Euclid’s postulates is prepapred and collected from varius resources to help the students.
Euclid’s postulates were :
Postulate 1 : A straight line may be drawn from any one point to any other point.
Axiom 5.1 : Given two distinct points, there is a unique line that passes through them.
How many lines passing through P also pass through Q (see Fig. 5.4)? Only one, that is, the line PQ. How many lines passing through Q also pass through P? Only one, that is, the line PQ. Thus, the statement above is self-evident, and so is taken as an axiom
Postulate 2 : A terminated line can be produced indefinitely.
Postulate 3 : A circle can be drawn with any centre and any radius.
Postulate 4 : All right angles are equal to one another.
Postulate 5 : If a straight line falling on two straight lines makes the interior angles on the same side of it taken together less than two right angles, then the two straight lines, if produced indefinitely, meet on that side on which the sum of angles is less than two right angles.
