• Well, parallel lines do not intersect. So the lines should never touch.
• Hey, how do you know if lines are parallel?
• Hey how do I know if my triangle has an acute angle?
• Well, an acute angle measures less than 90 degrees. And it looks like your triangle is acute.
• Maybe I can help? A perpendicular line is when two lines intersect so that the angles formed are right angles.
• A right angle measures at 90 degrees.
• I do not know how to make perpendicular lines!
• What is a right angle?
• If the points are on the same line then they are collinear points.
• How do i know if points are collinear points?
• What are coplanar points?
