No. If you made a parallelogram with congruent sides it wouldn't necessarily have congruent angles. A square has to have congruent angles as well as congruent sides.
It all depends on what kind of polygon it is. It may have no congruent sides or all congruent sides.
They are sometime congruent because a square is a parallelogram and its sides are congruent and a rectangle is one and its sides aren't congruent.
No. The word congruent is not applied to sides or angles.
Trapezoid.
No, rectangles do not have congruent sides. Squares have congruent sides.
No. If you made a parallelogram with congruent sides it wouldn't necessarily have congruent angles. A square has to have congruent angles as well as congruent sides.
Every cube has six congruent sides. If it doesn't have six congruent sides, then it's not a cube.
It has 2 congruent sides
It has four congruent sides.
A parallelogram with congruent sides is a rhombus.
It can have two congruent sides but does not have to.
No, it has 4 congruent sides.
A parallelogram has two pairs of congruent sides, and the opposite sides are congruent.
No. A rectangle has opposite sides congruent. If consecutive sides are also congruent, then your rectangle is a square.
It all depends on what kind of polygon it is. It may have no congruent sides or all congruent sides.
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.
