They can never be parallel. They may or may not be congruent, depending on the specific triangle.
triangle sides are congruents, not parallel.
Scalene Triangle- a triangle with no congruent sides Isosceles Triangle- a triangle with two congruent sides Equilateral Triangle- a triangle with three congruent sides
an isosceles triangle
That is simply not true. An isosceles trapezium, which is an isosceles triangle with its odd vertex chopped off by a line parallel to its base will have its non-parallel sides congruent. Also, there is nothing to prevent one (or both) of the sloping sides being congruent to one of the parallel sides.
Any polygon with 2n sides (n integer) where opposite sides are parallel, will have its opposite angles congruent.
Parallelogram -- 2 pairs of parallel sides Trapezoid -- exactly 1 pair of parallel sides Rhombus -- 4 congruent sides Rectangle -- 4 angles congruent Square -- four angles and sides congruent
A scalene triangle has no congruent sides. An equilateral has all equal sides, and an isosceles triangle has two of three sides equal.
Isosceles Triangle - 2 congruent sides Equilateral Triangle - all three sides are congruent Scalene triangle - no sides are congruent
A triangle with two congruent sides is an isoscelestriangle. But an equilateral triangle has two congruent sides. (It actually has three congruent sides.) And isosceles triangle is generally described as a triangle with exactly two congruent sides.
A triangle that has no congruent sides is a Scalene triangle.
A triangle which has no two sides congruent is called a Scalene Triangle.
a triangle without any congruent sides is a scalenetriangle
