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.

True or false Perpendicular lines form straight angles?
What is a 'Straight Angle'???? Perpendicular lines meet at 90 degrees ( right- angles).
What angels are in parallel lines?
straight angles
What is the fifth postulate of Euclid's?
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."
How many angles are formed when two lines intersect don't count straight angles?
If you draw two lines intersecting, you'll see that they create 4 angles.
What are Lines that cross each other?
intersecting lines...

Two lines meet angles are?
Angles in the straight line
What angels are in parallel lines?
straight angles
Lines are lines that form acute or obtuse angles at the point of inter sections?
Or right angles. Or, technically, straight angles as well
Is any line a straight angle?
Straight lines are straight angles (180 degrees)
Two lines meet at right angles are?
Two straight lines that meet at right angles are perpendicular.
What are lines thast intersect and do not form right or straight angles?
Intersecting lines
What lines are lines that form acute or obtuse angles?
Straight lines! if i didn't answer correctly tell me!
How many angles are formed when two lines intersect not counting straight angles?
4
Perpendicular lines form four straight angles?
False
What is the name of a figure without angles or straight lines?
A Circle
How can you determine if two lines are parallel or perpendicular?
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.
