An isosceles triangle has no parallel sides but 2 of its 3 sides are equal in length
A tetrahedron
yes
parallelogram
No. A square has 2 sets of parallel sides and FOUR RIGHT ANGLES.A rhombus has two sets of parallel sides and NO right angles.
No. A parallelogram has two sets of parallel sides.
No triangle has parallel sides but an isosceles triangle has two equal sides of the same lengths.
Nope, never. Parallelograms are classified as having 1 or 2 sets of parallel sides, not triangles.
A quadrilateral or a pentagon can have up to 2 pairs of parallel sides.A hexagon or heptagon can have up to 3 pairs of parallel sides.and so on.So, apart from a triangle, any polygon can have two sets of parallel sides.
Any shape that is not a triangle may have 2 parallel sides, although regular polygons only have parallel sides when the number of sides is even. For a quadrilateral, a trapezoid(UK trapezium) has 1 set of parallel sides and a parallelogram (either a rhombus, rectangle, or square) has 2 sets of parallel sides.

rhombus
A square (i am pretty sure) has 2 sets of parallel sides and four parallel sides.
Answer: 2 parallel lines you dig Answer: None of the sides can be parallel to any of the other sides.
No triangle has two parallel sides.None but it does have 2 sides of equal length and 2 angles of equal measure.
