angle bisector
All of the three sides of a triangle can be parts of parallel lines; it's just that no two of them can be parallel with each other. They can be parallel to some other line(s). In plane geometry parallel lines cannot form the sides of a common triangle.
Answer: 2 parallel lines you dig Answer: None of the sides can be parallel to any of the other sides.
Two lines are parallel if they never cross one another. Another way to tell if they are parallel is if they have the same slope. Also, if the same line intersects both of them at a 90 degree angle, they would be parallel (in other words, if both lines are perpendicular to a common line, they are paraellel).
Yes. Provided the first two planes are parallel, the third plane can be arranged so that it intersects both of the others.
Please make the question more specific, if a triangle has two lines on one side it means it is parallel to the other. Im not sure what you're asking. Lbui20
If a line is parallel to one side of a triangle and intersects the other two sides, then it divides those sides proportionally
Never, there are no true "opposite sides" on a triangle as each side intersects the other two at a point. Were two of the lines parallel, the triangle would be missing a point and would not be a closed shape.
Converse of the triangle proportionality theorem APEX :)
Non-parallel.
A triangle has no sides parallel to each other.
Yes, it does. And it makes equal angles with both of them.(We're talking about straight lines, in a plane.)
Like all other triangles it has no parallel lines.
No, A parallelogram has four sides, with opposing sides being parallel to each other. A triangle only has three sides, none of which can be parallel to each other.
How about the diagonals of a polygon or a transversal line cutting through parallel lines.
No side of a triangle is ever parallel to any other side of the same triangle.

There are no parallel lines in any triangle but a right angle triangle has perpendicular line that meet each other at 90 degrees.
