I assume you mean 4 congruent sides or 2 pairs of congruent sides.. (There are no 4-sided figures with 8 sides.) A square.
It has four 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.
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.
No, it means they have either 2 sides and 1 angle congruent, 2 angles congruent, 2 angles and a side congruent, or 3 sides congruent.
Four sides of the same size.
If two opposite sides are congruent in length and direction then they are parallel sides. THat would mean the other two sides are congruent making 4 parallel sides or a parallelogram
Two pairs of congruent angles and one pair of congruent sides ( sides not between the pairs of angles ).
I assume you mean 4 congruent sides or 2 pairs of congruent sides.. (There are no 4-sided figures with 8 sides.) A square.
No, rectangles do not have congruent sides. Squares have congruent sides.
Yes. This is because: Since the opposite sides are congruent, that would mean 2 sides are congruent with the others and 2 more sides are also. This takes up all four sides, which makes all of the sides congruent in the square. If you still do not get it, follow up on Mathisfun.com and it will give you explanations on why. -Savanna :D
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.
If you mean on opposite sides yes. There are 2 pairs of congruent angles.
Yes. It is still a quadrilateral as long as it still has four sides, and they can be congruent if all of the sides are equal. It does not mean that All of the angles have to be right.
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
