Plss... Can someone give me the easy explanation of Euclid's 5th definition about plane surface???
Euclid's Definitions
A point is that which has no part.
• A line is a breadth-less length
• A straight line is a line which lies evenly with the points on itself.
• A surface is that which has length and breadth only
. • The edges of a surface are lines. A plane surface is a surface which lies evenly with the straight lines on itself.
