No.
An impossibility. By definition a quadrilateral with 4 congruent sides must have congruent adjacent angles.
Square
A quadrilateral has 2 pair of congruent angles and 4 congruent sides. What is the name of the quadrilateral
No, not every quadrilateral is a kite. A kite is a specific type of quadrilateral that has two pairs of adjacent sides that are congruent. Other types of quadrilaterals, such as rectangles, squares, and parallelograms, have different sets of congruent sides.
always
Not necessarily. They can, but don't have to. A quadrilateral which does have congruent sides is called a rhombus.
False. If both pairs of opposite angles of a quadrilateral are congruent then the quadrilateral is a parallelogram.
It cannot. There is no way to draw a quadrilateral where 3 sides are congruent.
In short, no. Similar shapes are shapes in which all corresponding angles congruent regardless of the length of the sides. Congruent shapes have congruent corresponding angles and corresponding sides. In effect congruent shapes is a special condition of similar shapes.
square
There are two types of quadrilaterals that are formed when two congruent equilateral triangles are joined. These shapes are rhombus and parallelogram.
A square would fit the given description.
