... This can be done via knowledge of trigonometric functions or with the Pythagorean Theorem. The teacher may need to provide guidance: a good starting point would be to draw some triangles, as in the solution, and determine whether or not these special cases are equilateral. The task can be naturally ...

Let`s Learn About Triangles!
... The best way to learn something is to teach it to someone else! Find a friend to work with, and teach them each of these triangles. Be sure to explain why: “It’s a right angled, because one of the angles is 90 degrees, and it’s isosceles, because the other two angles are identical, so it’s a right a ...

Remarks on dihedral and polyhedral angles
... three planar faces to take any value between 0 and 180 degrees. More generally, one can consider the corners of other solid objects as well; for example, the top of a pyramid with a square base can be viewed as defining a 4 – faced corner, and one can do the same for the top of a pyramid whose base ...
