Answer: A quadrilateral is a polygon in Euclidean plane geometry with four edges (sides) and four vertices (corners). Other names for quadrilateral include quadrangle (in analogy to triangle), tetragon (in analogy to pentagon and hexagon), and 4-gon (in analogy to n-gons for arbitrary values of n). A quadrilateral with vertices {\displaystyle A}A, {\displaystyle B}B, {\displaystyle C}C and {\displaystyle D}D is sometimes denoted as {\displaystyle \square ABCD}{\displaystyle \square ABCD}.
The word "quadrilateral" is derived from the Latin words quadri, a variant of four, and latus, meaning "side".

In geometry, a quadrilateral can be defined as a closed, two-dimensional shape which has four straight sides. The polygon has four vertices or corners. We can find the shape of quadrilaterals in various things around us, like in a chess board, a deck of cards, a kite, a tub of popcorn, a sign board and in an arrow.
Step-by-step explanation:
What do you call a quadrilateral which has 4 equal sides and 4 right angles?
Rectangle: A quadrilateral with four right angles; a rectangle is a type of parallelogram. Square: A quadrilateral with four congruent sides and four right angles; a square is both a rhombus and a rectangle. Trapezoid: A quadrilateral with exactly one pair of parallel sides (the parallel sides are called bases)
Which quadrilaterals have 4 sides of equal length?
A rhombus is a quadrilateral with 4 equal sides. A shape with four sides of equal length.
What are the 4 properties of a quadrilateral?
A quadrilateral should be closed shape with 4 sides. All the internal angles of a quadrilateral sum up to 360°
...
Rhombus
Opposite angles are equal.
All sides are equal and, opposite sides are parallel to each other.
Diagonals bisect each other perpendicularly.
Sum of any two adjacent angles is 180°
What does a quadrilateral shape look like?
A Quadrilateral has four-sides, it is 2-dimensional (a flat shape), closed (the lines join up), and has straight sides.
What is a quadrilateral with no square corners?
The shape has no square corners . Justin can draw a rectangle or a parallelogram . parallelogram a quadrilateral with 2 pairs of parallel sides and 2 pairs of sides that are the same length .
Hope this is useful for you.
Answer:
Quadrilaterals were invented by the Ancient Greeks. It is said that Pythagoras was the first to draw one. In those days quadrilaterals had three sides and their properties were only dimly understood. It was the genius of the Romans to add a fourth side and they were the first to make a list of the different kinds of quadrilaterals but it wasn't until 1813 that an English mathematician, J.P. Smith, discovered the trapezium. Quadrilaterals remain a rich source of investigations for researchers, the best known unsolved problem being to find a general formula for the number of interior angles.
