Do diagonal of a quadrilateral always intersect?
Not always. They would only intersect when the internal angles are each less than 180 degrees - which not all quadrilaterals have.
How can intersect but not perpendicular?
When lines cross at 90 degrees, they are perpendicular. Anything less than 90 degrees, or anything more than 90 degrees, is not perpendicular. An example of a perpendicular intersection would be a plus sign + . An example of a non-perpendicular intersection is the letter X . Hope this helps.
When parrarel lines meets?
For most purposes in algebra and geometry, but especially geometry, parallel lines never meet. This should be the answer you give on nearly every question. However, speaking realistically, parallel lines can meet on planes of negative and positive curvature. An example of positive curvature would be a sphere; on a sphere, if you try to draw a triangle, the interior sum would be more than 180degrees and parallel lines would intersect. Similarly, on a plane of negative curvature like that of a surface of a saddle, the sum of the measures of the triangle would be less that 180 degrees and once again parallel lines will intersect.
What is a Angle Less than 90 degrees Called?
A angle less than 90 degrees is a acute angle.
What a perpendicular lines?
Perpendicular lines are lines that cross each other at 90 degree angles.For example, the letter T.The lines in the letter V are not perpendicular because the angle between them is less than 90 degrees.
Give 3 classification of technology?
"right angle" is two lines that intersect at 90 degrees "acute angle" is when 2 lines meet at less than 90 degrees "obtuse angle" is when lines meet at an angle more than 90 degrees , a straight angle is when 2 lines meet at exactly 180 degrees.
Do diagonal of a quadrilateral always intersect?
Not always. They would only intersect when the internal angles are each less than 180 degrees - which not all quadrilaterals have.
How can we rewrite Euclid's fifth postulate?
Euclid's fifth postulate: If two lines are drawn which intersect a third in such a way that the sum of the inner angles on one side is less than two right angles, then the two lines inevitably must intersect each other on that side if extended far enough.It can be rewritten: If two lines are drawn which intersect a third at angles of 90 degrees, the two lines are parallel and will not intersect each other.It has also been rewritten as Playfair's axiom:In a plane, given a line and a point not on it, at most one line parallel to the given line can be drawn through the point.
How can intersect but not perpendicular?

What is an angle more than 180 degrees and less than 360 degrees called?
An angle that is more than 180 degrees and less than 360 degrees is called a "reflex" angle.NoteAngles less than 90 degrees are called "acute" angles. An angle that is exactly 90 degrees is called a "right" angle.Angles that are more than 90 degrees but less than 180 degrees are call "obtuse" angles.An angle that is exactly 180 degrees is called a "straight line".Angles that are more than 180 degrees and less than 360 degrees are called "reflex" angles.

What is an angle that measures more than 90 degrees but less than 180 degrees called?
An angle that measures more than 90 degrees but less than 180 degrees is called an "obtuse" angle. Note Angles less than 90 degrees are called "acute" angles. An angle that is exactly 90 degrees is called a "right" angle. Angles that are more than 90 degrees but less than 180 degrees are call "obtuse" angles. An angle that is exactly 180 degrees is called a "straight line". Angles that are more than 180 degrees and less than 360 degrees are called "reflex" angles.
What is the range of measures formed by 2 intersecting lines?
Greater than 0 degrees, but less than 180 degrees. ;)
Where do cirques intersect?
Cirques could intersect at an intermediate ridge. This would be less common.
What is a Angle Less than 90 degrees Called?
A angle less than 90 degrees is a acute angle.
What is the difference between elephant and mammoth tusk?
The cross-section of proboscidean tusks reveal natural grain lines, called "Schreger lines." The angle at which these lines meet each other can be measured - if it is an angle less than 90 degrees, it is a fossil mammoth tusk. If the lines meet in more than 100 degrees, then it is an elephant tusk.
What is a triangle that has one angle less than 90 degrees?
If all three angles are less than 90 degrees, then it is called an Acute Triangle. If two angles are less than 90 degrees and the other one is 90 degrees, then it is called a Right Triangle. If one angle is more than 90 degrees and the other two are less than 90 degrees, then it is called an Obtuse Triangle. Hope this helps!
