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.

Angles in the straight line
straight angles
Or right angles. Or, technically, straight angles as well
Straight lines are straight angles (180 degrees)
Two straight lines that meet at right angles are perpendicular.
Intersecting lines
Straight lines! if i didn't answer correctly tell me!

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.
