In this publication we approach basic principles of plane geometry:
Tales of axioms with the relations of angles in triangles, similar triangles, Pythagoras theorem.
inscribed angles in a circle and its relations with central angles.
Angles tangent to the circle and its relations with central angles.
proportional segments.
basic trigonometry concepts with sine and cosine calculations at notable angles.
Calculations of sines and cosines tables.
Regular Polygons inscribed in the circle with studies of the equilateral triangle and square with calculations heights, apótemas, areas.
Study generic regular polygon with calculations inscribed angles, side lengths, apothem, circumscribed circle radius, area, perimeter, height.
