G.14 construct a segment
Construct a segment / A B / between any two points A, B.
G.15 construct a circle
Construct a circle ( A B ) with center A and defining radius point B.
G.18 extend a segment
Extend a segment / A B / continuously along a line [ A B ] to / B C /.
G.38 right angles are equal
All right angles are equal.
G.55 parallel postulate
Two lines intersected by a transversal with interior angles on one side summing to less than two right angles meet on that side.
G.14 construct a segment
Construct a segment / A B / between any two points A, B.
G.14 construct a segment
To draw a straight line from any point to any point.
G.15 construct a circle
To describe a circle with any centre and distance.
G.15 construct a circle
Construct a circle ( A B ) with center A and defining radius point B.
G.18 extend a segment
Extend a segment / A B / continuously along a line [ A B ] to / B C /.
G.18 extend a segment
To produce a finite straight line continuously in a straight line.
G.38 right angles are equal
That all right angles are equal to one another.
G.55 parallel postulate
That, 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.
