a square
I assume you mean 4 congruent sides or 2 pairs of congruent sides.. (There are no 4-sided figures with 8 sides.) A square.
A parallelogram is a four sided figure. that has congruent angles and all sides are parallel
if the angles of a figure are the same but the sides aren't, it is similiar. Congruent is angles and sides exactly the same
A quadrilateral is a4-sided figure with no congruent sides.
A four-sided polygon with all sides congruent and with four right angles is a square.
A four-sided polygon with four congruent sides and four equal angles is a square
a regular hexagon... it has to be regular to have the 6 sides congruent.
quadrilateral--a four-sided figure, any length sides, any angles trapezoid--one pair of parallel sides, any length sides, any angles parallelogram--two pairs of parallel sides, opposite sides congruent, opposite angles congruent rectangle--two pairs of parallel sides, opposite sides congruent, all angles are right angles (90 degrees) rhombus--two pairs of parallel sides, all sides congruent, opposite angles congruent square--two pairs of parallel sides, all sides congruetn, all angles are right angles (90 degrees)
If only two sides of one figure are congruent to two sides of another figure, you can say nothing about the opposite angles.
No. A trapezoid is a 4-sided flat shape with straight sides that has a pair of opposite sides parallel. The opposite angles not congruent.
Square.
A similar figure has the same interior angles as a congruent figure but its sides are in proportion to a congruent figure.
