Is perpendicular two lines that cross?
Not only that; to be "perpendicular", they have to cross at an angle of 90 degrees.
Why can there only be one right angle in a triangle?
Because a right angle has to have 2 lines.
What is the difference between perpindicular and intersecting lines?
Intersecting lines can cross at any angle. Perpendicular lines cross or meet at 90 degrees only.
Which triangle is the only triangle that has perpendicular lines?
The Right Triangle. Perpendicular lines make a right angle.
Are intersecting lines alway perpendicular?
Form right angles
How many and what type of angles do two perpendicular lines make?
only one angle, Right angle.....
What is a polygon with only one set of perpendicular lines?
A right angle triangle
What are the three relationships for two straight lines in the same plane?
Well, there are really only two: parallel and intersecting. Parallel lines go in the same direction and never cross; intersecting lines do cross (or intersect). However, a third relationship, that's actually a special case of intersecting lines, is the case of perpendicular lines. Perpendicular lines are those that make four right angles when they intersect. Really, it's enough if you know that only one of the angles is a right angle - the rest follow automatically.
What is the different of a perpendicular lines and intersecting lines?
The only difference between perpendicular lines and intersecting lines is that perpendicular lines create a right angle at the point of intersection.
Do perpendicular sides ever meet?
Only once at, a right angle. Paralell lines never meet.
What polygon has 1 right angle and only 1 set of parallel lines?
There are lots of polygons like that. If by 1 right angle, you mean exactly 1 right angle, there are no such quadrilaterals, but there are pentagons (in fact n-gons for all n>=5.)
Is there a parallelogram with only one right angle?
No, because all lines need to be parallel from the one they're across.
