The 3 names for this figure are:
1. Square - all sides are parallel, there are 4 right angles, and all the sides are the same length. All squares are quadrilaterals and parallelograms.
2. Quadrilateral - 4 sides. NOT all quadrilaterals are squares, however.
3. Parallelogram - all sides are parallel. NOT all parallelograms are squares, however.

Their are many names that go with Tristan, and the popular ones can be found online. Some examples are: Alexander, Cole, James, Shane, Lee, Samuel, Robert and Daniel.
The basic functions are sine, cosine, tangent, cosecant, secant and cotangent. In addition, there are their inverses, whose full names use the prefix "arc" [arcsine, arc cosine, etc] but are more often written as sin-1, cos-1 and so on.
No. For that matter, he didn't really have a last name. His name was Pythagoras. If anyone wanted to make sure that he didn't get confused with some other Pythagoras, they'd say something like "Pythagoras of Samos" (except, of course, that they'd say it in Greek: Î?υθαγόρας ὁ Σάμιος).The reason we have last names, middle names, etc. now is to avoid any confusion of this sort. Pointing up the need is the fact that there actually was another (semi-) famous Pythagoras living in Samos who was a sculptor and, to make matters worse, according to Pliny the Elder (see, there's another one we need to add a distinctive to; the modern system is looking smarter and smarter) he apparently looked a lot like the philospher/mathematician.
A square, rectangle, or quadrilateral
equal angle
A square, rectangle, or quadrilateral A square, rectangle, or quadrilateral
Different pairs of angles have different names.
They are rhombus and parallelogram.
Quadrilateral, rectangle, square
Not exactly. They are two names for the same shape. The typical shape consists of a four-sides figure with opposite sides (and angles) equal. Each pair of parallel sides are the same length.
square or rhombus
a rhombus, a quadrilateral without right angle, a quadrilateral with equal opposite parallel sides but no right angles
Acute angles do not have specific names.
-- both have four sides -- both have four angles -- both have at least one pair of parallel sides -- both have two sets of equal angles -- both have names composed of 9 letters -- both have the letters 'r', 'e', 't', and 'a' in their names
A quadrangle or quadrilateral (a shape with 4 angles or 4 sides, respectively). Special names normally come in when you DO have special characteristics, not when you don't.
