Does a triangle have parallel and perpendicular sides?
A triangle has no parallel sides but in the form of a right angle triangle it has perpendicular lines that meet at right angles which is 90 degrees.
How many parallel lines and angles does a triangular prism have?
It has 1 set of 3 parallel lines and 3 sets of 2 parallel lines, and 18 angles (3 sides meet at each vertex)
Do perpendicular lines meet at right angles?
Yes perpendicular lines meet at right angles of 90 degrees
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."
What is formed by two real number lines that intersect at a right angle?
A perpendicular line is formed when two lines meet at a right angle. Opposite angles in a perpendicular line are parallel to each other.
How many parallel lines does a right angle have?
A right angle has no parallel lines, but it does have perpendicular lines that meet at right angles.
Are perpendicular parallel line meet at 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.
Which do you use when parallel lines form similar triangles?
Triangles do not have parallel lines but as right angles triangles they do have perpendicular lines that meet at 90 degrees.
How do you calculate parallel line angles?
Parallel lines do not meet and so do not form angles.
Do parallel lines meet at a right angle?
No, parallel lines do not meet at a right angle. In theory, parallel lines never meet. In practice, parallel lines on earth could meet at the North Pole and/or the South Pole. Perpendicular lines meet at a right angle.
How many parallel line segments does a right angle have?
Normally none but it does have perpendicular lines that meet at right angles.
How many parallel and perpendicular lines are in a parallelogram?
A parallelogram has 2 pairs of parallel lines and in the form of a rectangle it has 2 pairs of parallel lines and 4 perpendicular lines that meet at each of its corners at right angles.
Does a triangle have parallel and perpendicular sides?
A triangle has no parallel sides but in the form of a right angle triangle it has perpendicular lines that meet at right angles which is 90 degrees.
What are lines that meat at right angles?
Perpendicular lines meet at right angles
Two lines meet at right angles are?
Two straight lines that meet at right angles are perpendicular.
How many angles does parallel have?
Parallel lines do not meet and so cannot form an angle.
How many parallel lines and angles does a triangular prism have?
It has 1 set of 3 parallel lines and 3 sets of 2 parallel lines, and 18 angles (3 sides meet at each vertex)
