A quadrilateral is a quadrilateral shape with four sides and four angles. It is the only quadrilateral with four right angles.
Here are some key properties of quadrilaterals:
Opposite angles are congruent: This means that the angles opposite the two longest sides of a quadrilateral are equal in measure.
Diagonals bisect each other: The diagonal lines of a quadrilateral bisect each other at right angles. This means that the opposite angles are congruent and the diagonals bisect each other at right angles.
Perimeter: The perimeter is the total length of all four sides of a quadrilateral. The perimeter can be found by adding the lengths of all four sides.
Area: The area of a quadrilateral is the amount of space inside the shape. The area can be found by multiplying the length of one side by the area of the opposite triangle.
Diagonals: The diagonal of a quadrilateral divides the shape into two congruent triangles.
Symmetry: A quadrilateral is symmetric, meaning it looks the same when viewed in the middle. The center of symmetry is the point of intersection of the diagonals.
Angles: A quadrilateral has four right angles, which means that the angles are all equal in measure.
Circumcenter: The circumcenter is a point equidistant from all four vertices of a quadrilateral. The circumcenter is located at the center of the circle that passes through the vertices
