Learn more about the angles of the rectangle, the interior angles, the diagonal angles, and the sum of the angles of the rectangle with concepts, properties, formulas, and examples.

A rectangle is a four-sided flat shape where every angle is a right angle (90°).

Jul 23, 2025 · All four angles are right angles (90°). The opposite sides of a rectangle are equal in length and parallel to each other. A rectangle is a two-dimensional flat shape. Here, sides AB …

A rectangle is a parallelogram with 4 right angles. Now, since a rectangle is a parallelogram, its opposite sides must be congruent and it must satisfy all other properties of parallelograms

A rectangle is a quadrilateral whose interior angles are all equal. Since the sum of the interior angles of a polygon is \ ( 360^\circ \), it follows that each of the interior angles is a right angle.

Discover the angles of a rectangle, their properties, and how to find them. Learn all about rectangle angles for students in 2025-26.

In Euclidean plane geometry, a rectangle is a rectilinear convex polygon or a quadrilateral with four right angles. It can also be defined as: an equiangular quadrilateral, since equiangular …

A rectangle has 2 lines of symmetry and a rotational symmetry of order 2, which means that it can be rotated in such a way that it will look the same as the original shape 2 times in 360°.

All angles in a rectangle are right angles, which means they measure 90 degrees. The two short sides of a rectangle are called the "legs," and the long sides are called the "long sides."

Like a square, a rectangle is a two-dimensional (or flat) rectilinear shape with four sides and four right angles. By a rectangle’s definition, opposite sides must be equal and parallel to each other.
