trapezium
A rectangle
Rectangle, parallelogram
A rectangle has 4 sides not the same length and 4 right angles.
No shape has four equal sides and four different angles - either there are two pairs of equal angles, or all four angles are the same; or all sides are not the same length.

No shape has four equal sides and four different angles - either there are two pairs of equal angles, or all four angles are the same; or all sides are not the same length.
A square has all 4 sides the same length and its angles measure the same as well. A rhombus has all 4 sides the same length as well and the angles measure the same as well too.
A rectangle. The opposite sides at least must be equal if all four angles are 90o.
A square.
A Rhombus
a square, quadrilateral or a cube.
Assuming that each vertex is used to connect exactly two sides, all two-dimensional shapes will have the same number of sides as vertices. So a shape with 4 sides will have 4 vertices and a shape with 3 sides will have 3 vertices. Think of a square (4 sides, 4 vertices) and a triangle (3 sides, 3 vertices).
