Pole trapezu - Matematyka Szkoła Podstawowa i Gimnazjum

In this video, I show how to identify the bases and legs of a trapezoid, what the height of a trapezoid is, and how to draw it correctly both inside and outside the figure, including for right trapezoids. I teach how to label the lengths of sides and heights with the letters A, B, and H according to technical mathematical notation. I present the formula for the area of a trapezoid as (A+B)⋅H/2 and demonstrate step by step how to apply it in calculations using units of length and area, with examples based on given geometric data. TABLE OF CONTENTS: 1. What is a trapezoid 2. Bases and legs of a trapezoid 3. Height of a trapezoid – definition and drawing 4. Height on the extension of the bases 5. Height in different types of trapezoids 6. Right trapezoid – special case of height 7. Formula for the area of a trapezoid 8. Example 1 – trapezoid with given lengths 9. Example 2 – right trapezoid 10. Example 3 – inverted trapezoid CONTINUATION OF THIS VIDEO here: [   • Dokończenie filmu p.t. Pole trapezu  ](   • Dokończenie filmu p.t. Pole trapezu  ) You can find more on the playlists: [   • POLE POWIERZCHNI  ](   • POLE POWIERZCHNI  ) and [   • GEOMETRIA NA PŁASZCZYŹNIE  ](   • GEOMETRIA NA PŁASZCZYŹNIE  ) EASY ACCESS to all my math lessons is available on my website: [www.matmagwiazdy.pl](http://www.matmagwiazdy.pl) On this channel, you will find a complete course – 100% of the lessons – in Mathematics for Primary School, High School, and Technical School.
