Euclid’s Definitions, Axioms and Postulates
Consider the three steps from solids to points (solids-surfaces-lines-points). In
each step we lose one extension, We can get online geometry tutor also called a dimension. So, a solid has threedimensions, a surface has two, a line has one and a point has none. Euclid summarized solved geometry problems these statements as definitions. He began his exposition by listing 23 definitions in
Book 1 of the ‘Elements’. A few of them are given below :
1. A point is that which has no part.
2. A line is breathless length.
3. The ends of a line are points.
4. A straight line is a line which lies evenly with the points on itself.
5. A surface is that which has length and breadth only.

6. The edges of a surface are lines.
7. A plane surface is a surface which lies evenly with the straight lines on itself.
