I assume you mean 4 congruent sides or 2 pairs of congruent sides.. (There are no 4-sided figures with 8 sides.) A square.
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 parallelogram is a four sided figure. that has congruent angles and all sides are parallel
A four-sided polygon with all sides congruent and with four right angles is a square.
a regular hexagon... it has to be regular to have the 6 sides congruent.
If only two sides of one figure are congruent to two sides of another figure, you can say nothing about the opposite angles.
A similar figure has the same interior angles as a congruent figure but its sides are in proportion to a congruent figure.
A four-sided polygon with four congruent sides and four equal angles is a square
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)
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.
