A rectangle is a quadrilateral with four equal interior angles, each of which is a right angle. The opposite sides of a rectangle are equal and parallel to each other, with the interior angle of a rectangle at each vertex measuring 90°. The sum of all interior angles in a shape is 360°.
A rectangle contains four interior right angles, with angles A, B, C, and D equal to 90°. The diagonals of a rectangle are two diagonals that bisect each other and have equal lengths. The sum of the exterior angles of a rectangle is 90×4=360°, and the diagonals bisect each other.
A parallelogram with dotted lines from corner to corner can be used to understand the properties of a rectangle. Since the opposite sides are parallel and equal, the sum of its interior angle is 360∘. This means that the sum of all internal angles of a rectangle is 180° × (4 – 2) = 180° × 2 = 360°. For a rectangle, n=4, the sum of angles is (4–2)180 = 360 degrees. Each interior angle is 360/4 = 90 degrees.
A rectangle has four right angles, and the diagonals are equal, splitting it into four isosceles triangles. The diagonals do not meet at right angles, ensuring that the rectangle’s angles are equal.
