A basic term in physics, the electromagnetic spectrum defines the range of all possible frequencies of electromagnetic radiation. It covers the tremendous range of wavelengths and frequencies, from the very long radio frequencies to the extremely short wavelengths of gamma rays. Proved very handy in a lot of spheres, ranging

Angles are everywhere and in everything, from the room corners  to the engineer’s precise measurement of an engineering design. But what does it really mean, to say that two angles are congruent? Let’s dive deep into the matter of congruent angles, see whether vertical angles are congruent, and come up

In mathematics, rotation refers to a type of transformation that turns a figure around a fixed point, known as the center of rotation. Unlike other geometric transformations like translations (sliding) or reflections (flipping), rotation involves turning the figure around a point by a certain angle. This transformation is widely used
