Uses and Applications Tests and Exams

Time is very limited. Save time to find lengths of the sides

immediately.

How to Create Triplets 2 ways to do so:

Memorise by heart Use a formula

The triplets will also mostly follow the ratio 3:4:5, or any triangle similar to it.

Some Pythagorean Triplets 3:4:5 right triangle & all its similar triangles

6:8:10 triangle 9:12:15 triangle

5:12:13 right triangle & all its similar triangles 10:24:26 triangle

20:21:29 right triangle and all its similar triangles 40:42:58 triangle
