Perpendicular lines intersect each other at right angles which is 90 degrees.
A straight line has no right angles. But a square is actually a closed line with four right angles.
Parallel lines are lines that run side by side and never meet. Perpendicular lines are lines that meet in one point, forming four right angles around the point.
A perpendicular line, or a line at right angles.
An angle is the measurement between two lines that share a point. A right angle, which consists perpendicular lines, is exactly 90 degrees. A straight line is 180 degrees (two right angles combined).
Perpendicular.
Exactly upright or vertical; pointing to the zenith; at right angles to the plane of the horizon; extending in a right line from any point toward the center of the earth., At right angles to a given line or surface; as, the line ad is perpendicular to the line bc., A line at right angles to the plane of the horizon; a vertical line or direction., A line or plane falling at right angles on another line or surface, or making equal angles with it on each side.

Draw any straight line through the point. The sum of the angles at the point are the sums of the angles on each side of the line - which are known to be 180o. Thus: the sum of the angles at the point = the sum of the angles of each side of the line = 180o + 180o = 360o The sum of the a

A parallelogram with right angles is a rectangle.---------------------------------To construct a right angle using a straight edge and a pair of compasses:Draw the first lineExtend the first line beyond the point where the right angle is required (call this point O).With the point of the compasses on the point where the right angle is to be constructed draw a small arc on the straight line either side of point O; call the points where these arcs cross the straight line as A and B.Open the compasses to a larger widthWith the point of the compasses on one of points A and b (say A) draw one arc above the line roughly in the middle between points A and B (above point O).With the point of the compasses on the point of A and B (say B) draw an arc to intersect the last arc just drawn (above point O); call this point CUsing the straight edge, join point O to point C, forming a right angle.rub out the extended bit of the line beyond point O that was used to construct the right angle.
First you draw a square. A square has 4 right angles. If you draw a line above one of the right angles and rub out the angle which you have drawn a line above you have a pentagon with 3 right angles.
A line at right angles to another line.

Perpendicular lines intersect and form a right angle. The lines on a square are perpendicular to each line that it touches.
