Explaining the geometry curriculum, starting with angles, then the triangle, including its auxiliary lengths, such as the bisector, median, and height, in addition to the properties of similarity, area, and the right triangle, the Pythagorean and Euclid theorem, and then the special polygons and quadrilaterals, such as the trapezoid, parallelogram, rhombus, square, and rectangle. Then comes the circle, the properties of angles and lengths in it, along with the area and perimeter, and then analytical geometry in the coordinate plane and the equation of a straight line.
