What angle is formed at the intersection of the diagonals of a rhombus?

Mensuration is a branch of mathematics that deals with the measurement of two-dimensional (2D) and three-dimensional (3D) geometric figures and their parameters like length, shape, surface area, lateral surface area, volume, etc. In simple words, it outlines the principles of calculation based on algebraic equations, mathematical formulas, and also the properties of various geometric shapes. Circles, triangles, quadrilaterals, and pentagons are some examples of 2D geometric shapes, while spheres, cubes, prisms, cylinders, etc. are examples of 3D geometric shapes. Archimedes is known as the father of mensuration.
