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.
It has no paralel lines. A paralel line are two lines that never cross. If you notice, in a trinagle all lines are touching all other lines.
Two lines on two sides of a triangle typically indicate that those sides are parallel. This is known as a parallel line relationship. When two lines are parallel, they will never intersect, and they have the same slope. In the context of a triangle, this relationship can help determine other properties of the triangle, such as angles or side lengths.
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).
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.
A right angle triangle has no parallel sides
No side of a triangle is ever parallel to any other side of the same triangle.
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.
How about the diagonals of a polygon or a transversal line cutting through parallel lines.
