Can a triangle have parallel sides Why?
None. Parallel lines are lines that will never cross each other, no matter how long you make them.
Do all triangles have parallel sides?
A geometric shape has parallel sides if those sides do not meet or cross and the distance between them does not change. Parallel sides of a shape are opposite, or across from each other, and they would not intersect if they were extended infinitely beyond the confines of the shape.
Can any two sides of a triangle can be parallel?
No, we cannot say that the two sides of a triangle are parallel.
Which shape has parallel sides?
Some shapes that have parallel sides include the parallelogram, the rectangle, the square, the trapezoid, the hexagon, and the octagon.
Which shape never have parallel sides?
Triangles are shapes that have no parallel sides. All triangles will have three sides and it is impossible for any of them to be parallel.

How do you find a parallel triangle?
If a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally. If ¯DE∥¯BC , then ADDB=AEEC .
What shapes do not have parallel sides?
Triangles are shapes that have no parallel sides. All triangles will have three sides and it is impossible for any of them to be parallel.
What are parallel lines in a triangle?
A midsegment is parallel to one side of a triangle and divides the other two sides into congruent halves. The midsegment divides those two sides proportionally….Investigation: Triangle Proportionality.

Does a rectangle have parallel sides?
What is a rectangle? A rectangle is a quadrilateral with 4 right angles. A shape with four sides of equal length. The shape has two sets of parallel sides and has four right angles.
What do parallel lines in a triangle mean?
If a line parallel to one side of a triangle intersects the other two sides, then it divides the two sides proportionally. The converse is also true.

How many sides do triangles have?
three sides A triangle is a 3-sided polygon sometimes (but not very commonly) called the trigon. Every triangle has three sides and three angles, some of which may be the same.
What are the 3 sides of a triangle?
In a right triangle, the hypotenuse is the longest side, an "opposite" side is the one across from a given angle, and an "adjacent" side is next to a given angle. We use special words to describe the sides of right triangles.
How do you prove a triangle has parallel lines?
Triangle Proportionality Theorem Converse: If a line divides two sides of a triangle proportionally, then it is parallel to the third side.
How do you find the parallel lines of a triangle?
If a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally. If ¯DE∥¯BC , then ADDB=AEEC .
What is a shape that has no parallel sides?
A trapezoid is a quadrilateral with no parallel sides.
Which lines are not parallel to each other?
Skew lines are lines that are not coplanar, do not intersect, and are not parallel. Skew lines exist only in three or more dimensions.
What is example of parallel lines?
The real-life examples of parallel lines include railroad tracks, the edges of sidewalks, rails of a ladder, never-ending rail tracks, opposite sides of a ruler, opposite edges of a pen, eraser, etc.
How many sides does a triangle have?

Are all 3 sides of a triangle equal?
A triangle with all sides equal is called an equilateral triangle, and a triangle with no sides equal is called a scalene triangle.

Which line pairs are parallel?
The pairs of lines that do not intersect or meet at any point are called parallel lines. These lines lie on the same plane but do not intersect. The line segments or rays that lie on the same plane but do not intersect are also parallel.
Which of the following shapes that do not have parallel lines?
The American term for such a quadrilateral is a trapezium, and the British term is a trapezoid. It is a quadrilateral that has no parallel sides.

What shape has 2 pairs of parallel sides?
What is a parallelogram? A parallelogram is a quadrilateral with 2 pairs of parallel sides. In these figures, sides of the same color are parallel to each other.
How do you know if angles are parallel?
If two lines are cut by a transversal so the alternate exterior angles are congruent, then the lines are parallel. If two lines are cut by a transversal so the consecutive interior angles are supplementary, then the lines are parallel. Proof Ex.
How many shapes have no parallel sides?
All types of triangle, such as equilateral triangle, isosceles triangle and scalene triangle, have no parallel lines.. A kite is another shape that does not have parallel sides. Some shapes have many parallel sides. For example, a regular hexagon has three pairs of parallel sides.
