Web11 dec. 2024 · This works out perfectly: The measure of each internal angle of an equilateral triangle is 60 degrees, and 6 × 60 = 360, which is exactly what we need around a single point. Similarly for squares: Four squares around a single point at 90 degrees each gives us 4 × 90 = 360. But starting with pentagons, we run into problems. WebWe have found that students are able to recognise after 4 or 5 terms that the answer can be found by adding consecutive terms. For example: to find the 5th term you can either work out 1+2+3+4+5, or do 10 (the previous term) + 5.
