Euclid's first postulate related to
ATriangles
BParellel lines
CPerpendicular lines
DCircles
Answer:
B. Parellel lines
Read Explanation:
Euclid's postulates - To draw a straight line from any point to any point. - To produce a finite straight line continuously in a straight line - To describe a circle with any centre and distance - That all right angles are equal to one another - If a straight line falling on two straight lines make the interior angles on the same side less than two right angles, the two straight lines if produced indefinitely meet on that side on which are the angles less than the two right angles.
