An angle is formed when two rays meet at a common endpoint known as the vertex. The amount of rotation between the two rays determines the size of the angle. Angles are measured in degrees and are classified into types such as acute right obtuse and reflex angles.
In Class 6 Maths Chapter 8 on Playing with Constructions students learn about basic geometric constructions using a compass and ruler. The chapter covers drawing angles bisectors constructing perpendiculars and circles and understanding symmetry. Students also practice constructing various geometric shapes and understanding the properties of different constructions for accurate results.

When a square is rotated, it remains a square because its intrinsic properties are preserved. A square is defined by having four equal sides and four right angles (90°). Since rotation is a rigid transformation that does not change side lengths or angles, all sides remain equal and every angle stays at 90°. Therefore, even when rotated, the square maintains its defining characteristics.
