Which of the following best describes a basic postulate of euclidean geometry? a. all straight line segments have a midpoint. b. any straight line segment can be extended indefinitely. c. all right angles are formed from perpendicular segments. d. any two right angles are supplementary.
the sum of angles of triangle is 2 right angles. it means they are supplementary or when they add up gives 180 degree.
It is indeed A
The following best describes a basic postulate of the Euclidean geometry
Option first - All lines continue indefinitely.
One of the postulates of the Euclidean geometry states that any straight line segment can be extended indefinitely in a straight line. So according to this postulate, the first one is correct.
