Triple Geometry

Description: This course takes up the subject of triples, like 3,4,5, which represent the sides of right-angled triangles (e.g. 3² + 4² = 5²). Most of the techniques developed though are not restricted to integer-sided triangles. We see how to find two sides of a right-angled triangle given only one side, and the many applications of this, including in equations, in 2 and 3-dimensional geometry and astronomy (see contents below). The course is independent of any other of our courses and the content is not repeated in any of them. No calculator required.

You can join this course any time.

Enrolling in the course you have:
- a trainer to answer questions,
- regular tests,
- a certificate for those who pass.

Course start: You can join this course any time.

Mode: 100 % Online.
9 Video Lessons with online Tests (plus 14 optional Challenge Questions).
Self paced: watch videos at any time that suits you. Lessons are 20 minutes long on average. Each week has a test and there are additional exercises in the videos.

Suitability: The course is not based on any school curriculum and so would be suitable for anyone who:
             - is over the age of about 10 years,
             - seeks the challenge of something entirely different,
             - wishes to expand their thinking - perhaps to train for competitive exams,
             - wants to see new applications of Vedic mathematics.

Cost: $30.
