What is a counterexample for all intersecting lines form right angles?
Say angle 1 is 40 which means that if angle 3 is congruent then angle 3 is also 40 by definition of vertical angles. That would make angle 2 equal to 140 by definition of a linear pair and so angle 4 is congruent by vertical angles.
What 2 angles make a right angle?
two supplementary angles * * * * * NO! Supplementary angles sum to 180 degrees = 2 right angles. The correct answer is complementary angles.
What is a triangle with no right angles?
Equilateral Triangles do not contain right angles, since all angles in this shape are equal and it is impossible to make a triangle that consists of three 90 degress angles. Isosceles and Scalene may contain a right angle.
How do you draw a pentagon with 3 right angles?
Oh, dude, drawing a pentagon with 3 right angles is like trying to make a square with 5 sides. It's just not gonna happen in the world of geometry. You can have a pentagon with 5 equal sides, but throwing in those right angles is a big no-no.
Some triangles have three right angles?
no. The sum of the angles must be 180. 90+90+90=270. Plus, If you tried to make a triangle with 3 right angles, you would end up with an incomplete rectangle
How are perpendicular lines and intersecting lines alike and different?
they both have lines crossing each other which make angles. perpendicular lines make right angles while intersecting lines make other kinds
What kind of lines are lines that cross each other?
If they make right angles they are perpendicular. If they do not make a right angle, they are intersecting.
What kind of line makes use of rounded angles?
Right angles are formed by perpendicular lines. If the lines would extend, to make two intersecting lines.
Can you show me what a perpendicular lines look like?
They look like two intersecting lines that make four right angles. Like the two lines in this L.
What are lines that intersect which make acute and obtuse angles?
Non-perpendicular intersecting lines.
How are perpendicular lines and intersecting lines are different?
Perpendicular lines are a specific kind of intersecting lines. Intersecting lines are any two lines that cross through each other. Depending on how they cross each other, they may make angles from 170 degrees to 1 degree. Perpendicular lines are specifically two straight lines that cross each other at right angles, so that they create angles that are 90 degrees.
What type of angle is formed by perpendicular lines?
Right angles are formed by perpendicular lines. If the lines would extend, to make two intersecting lines, they would form four right angles. Perpendicular lines are written like this: . From its shape, you can already tell that it forms at least two right angles.
How are perpendicular lines different to intersecting lines?
Perpendicular lines have to intersect to make a right angle Like this: + Intersecting lines don't have to intersect to make a right angle Like this: X
What is two intersecting lines that make a right angle?
Perpendicular 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.
What is the difference between perpendicular and intersecting lines?
perpendicular crosses at a right angle, while intersecting lines don't
How are perpendicular lines and intersecting line?
Both lines intersect other lines, but the difference is a perpendicular line intersects another line at a 90 degree angle meanwhile the intersecting lines can meet at any angle
