An ear of a polygon is defined as a triangle formed by three consecutive vertices ,, of the polygon, such that its edge lies entirely in the interior of the polygon. The two ears theorem states that every simple polygon that is not itself a triangle has at least two ears. [1]
A polygon ear. One way to triangulate a simple polygon is based on the two ears theorem, as the fact that any simple polygon with at least 4 vertices without holes has at least two "ears", which are triangles with two sides being the edges of the polygon and the third one completely inside it. [5]
Greuze's "Retour sur soi-même" was an example of a bad likeness of the head of an old woman, because classical drawing theory was applied which was based on a young adult male's head. Merely adding wrinkles and a costume cannot help a poor likeness. The Moor, an etching by Jan de Visscher after a drawing by his brother Cornelis
An exterior angle of a triangle is an angle that is a linear pair (and hence supplementary) to an interior angle. The measure of an exterior angle of a triangle is equal to the sum of the measures of the two interior angles that are not adjacent to it; this is the exterior angle theorem. [34]
The strokes are the components of a letterform. [4] Strokes may be straight, as in k l v w x z, or curved, as in c o s.If straight, they may be horizontal, vertical, or diagonal; if curved, open or closed.

From the two angles needed for an isometric projection, the value of the second may seem counterintuitive and deserves some further explanation. Let's first imagine a cube with sides of length 2, and its center at the axis origin, which means all its faces intersect the axes at a distance of 1 from the origin.
