The first defines them as opposites, such that a statement cannot be both a simile and a metaphor — if it uses a comparison word such as "like" then it is a simile; if not, it is a metaphor. [ 1 ] [ 3 ] [ 2 ] [ 4 ] The second school considers metaphor to be the broader category, in which similes are a subcategory — according to which every ...
A Dictionary of Similes is a dictionary of similes written by the American writer and newspaperman Frank J. Wilstach. In 1916, Little, Brown and Company in Boston published Wilstach's A Dictionary of Similes, a compilation he had been working on for more than 20 years. It included more than 15,000 examples from more than 800 authors, indexing ...
Any two pairs of angles are congruent, [4] which in Euclidean geometry implies that all three angles are congruent: [a] If ∠ BAC is equal in measure to ∠ B'A'C', and ∠ ABC is equal in measure to ∠ A'B'C', then this implies that ∠ ACB is equal in measure to ∠ A'C'B' and the triangles are similar.
If every internal angle of a simple polygon is less than a straight angle (π radians or 180°), then the polygon is called convex. In contrast, an external angle (also called a turning angle or exterior angle) is an angle formed by one side of a simple polygon and a line extended from an adjacent side. [1]: pp. 261–264
Comparison of first and third-angle projections showing that related parts in the views are closer in third-angle. In first-angle projection, the object is conceptually located in quadrant I, i.e. it floats above and before the viewing planes, the planes are opaque, and each view is pushed through the object onto the plane furthest from it ...
Exterior angle – The exterior angle is the supplementary angle to the interior angle. Tracing around a convex n-gon, the angle "turned" at a corner is the exterior or external angle. Tracing all the way around the polygon makes one full turn, so the sum of the exterior angles must be 360°. This argument can be generalized to concave simple ...
Then one of the alternate angles is an exterior angle equal to the other angle which is an opposite interior angle in the triangle. This contradicts Proposition 16 which states that an exterior angle of a triangle is always greater than the opposite interior angles. [5]: 307 [3]: Art. 88
The exterior angle theorem is not valid in spherical geometry nor in the related elliptical geometry. Consider a spherical triangle one of whose vertices is the North Pole and the other two lie on the equator. The sides of the triangle emanating from the North Pole (great circles of the sphere) both meet the equator at right angles, so this ...
