Geometry in Mathematics

  • Description
  • Outcome
  • Certification
  • This free online Geometry course provides a comprehensive introduction to geometrical methods and techniques, covering angles, triangles, quadrilaterals, polygons, and more.


    It is ideal for complementing face-to-face classes, as a study guide, or for those who would like to refresh their knowledge of mathematics.

  • After completing this course you will have a good understanding of equilateral, isosceles, scalene, acute-angled, right-angled, and obtuse-angled triangles. You will know how to calculate different types of angles in circles, rectangles and triangles. You will gain a knowledge of quadrilaterals and the properties of a square, rectangle, parallelogram, rhombus, trapizium and kite. You will effectively learn the rotational symmetry of a polygon. This course will teach you about geometrical solids, such as spheres, hemispheres, toruses and prisms. You will understand transformations such as reflections and rotations.

  • All Alison courses are free to study. To successfully complete a course you must score 80% or higher in each course assessments. Upon successful completion of a course, you can choose to make your achievement formal by purchasing an official Alison Diploma, Certificate or PDF.
