Think about this: A straight angle makes 180 degrees, right? Straight lines, when measured by a compass, are also 180 degrees. So, yes, all straight angles are straight lines.

Q: Are all straight angles straight lines?

What is a 'Straight Angle'???? Perpendicular lines meet at 90 degrees ( right- angles).

straight angles

The 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."

If you draw two lines intersecting, you'll see that they create 4 angles.

If the two lines are parallel, they will never connect. A straight line drawn across those lines will intersect them at identical angles. If you have perpendicular lines, they intersect and all four angles that they make are 90 degrees.
