Can we say that all regular polygons are made from congruent isosceles triangles?
Please see below.
From the center of a regular polygon, say with
Observe that if center is joined to all the vertices, this forms
Hence, we can say that all regular polygons are made from congruent isosceles triangles.

No, not all regular polygons are made from congruent isosceles triangles. Regular polygons with an even number of sides (such as squares, hexagons, octagons, etc.) can be divided into congruent right triangles, but not necessarily isosceles triangles. However, regular polygons with an odd number of sides (such as equilateral triangles, pentagons, heptagons, etc.) can indeed be divided into congruent isosceles triangles.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
