Równoległoboki i romby - Matematyka Szkoła Podstawowa i Gimnazjum

In this video, I present the definition and characteristics of parallelograms and rhombs, demonstrate the differences between these figures using examples, explain the properties of the diagonals of parallelograms and rhombs, discuss how to draw a parallelogram based on the lengths of its sides using a ruler and compass, and demonstrate drawing a rhomb using two methods – based on the lengths of the sides and based on the lengths of the diagonals and their perpendicularity.
