Do two intersecting lines have to form four angles?
Yes. They do. I disagree with the answer above, no they do not > that is 2 intersecting lines and there are only 2 angles there so the person above it incorrect
What are angles formed by two intersecting lines and only share one vertex?
adjacent angles
Do intersecting lines form perpendicular angles?
Only when they intersect each other at right angles.
Do all intersecting lines form right angles?
No, This only happens when an intersecting line makes a plus sign.
What kind of angles are formed by two intersecting lines?
Only three types of angles can be formed by two intesecting lines. Obtuse, acute, and right.
What are two lines intersecting to form two lines?
They would be called intersecting lines.Intersecting lines form Vertically Opposite Angles. Each pair of opposite angles (sharing only a vertex) is congruent. Each of the four pairs of adjacent (sharing a side) angles forms a straight angle (they add to 180o).
Are intersecting lines alway perpendicular?
Form right angles
How are perpendicular lines different than intersecting?
Perpendicular lines are where a line crosses another line and forms 4 right angles on all 4 sides but a intersecting line only crosses another line
Why does a pair of intersecting lines cross only once?
They only cross once because intersecting lines are only supposed to INTERSECT at one point, hence the name intersecting lines
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.
Is it true that two lines with different slopes are perpendicular?
No. Only lines that intersect at 90 degree angles are perpendicular. Any other lines that cross each other are simply intersecting lines.
Can you draw lines that are parallel but not intersecting?
That's the only kind of parallel lines there are, non-intersecting!
