What is the abbreviation of rectangular?
RECT
How did the rectangle get its name?
From its right angle. right angle --> rect angle.
Do the diagonals of a rectangle bisect the vertexes?
No. Draw a rect. with dimensions of 1" by 2''. Note the angle formed by the diagonals. Now lengthen the rect. to 1'" by 10". The angle formed by the base and the diag. has to be reduced in order for the diagonal to travel to the new corner (with the same rect. height). This is not an actual proof. You can calculate the angle but I am not certain you can do it with geometry--need trig. With trig., knowing the two sides (you know the hypotenuse with geometry too so you could use any of the trig functions), you can calculate the tangent of the angle in the 1"x2" rect, it is 0.5000. The length of the base increases by 8" for the second rect., which changes the value of the tangent (0.10000) which in turn changes the degree of the angle. The diag. of a square bisects the vertex but no so with rectangles.
What is the volume of a 8ft x 12ft x 7ft Rect prism?

What makes a rectangle different from a parallelogram?
All four of the angles of a rectangle (and of squares) are right angles.(Its name comes from this : rect-angle.)
What does the root word rect mean?
Rectify is derived from the Latin "rectus", meaning "straight". Hence rectify means "to straighten" or by extension "to correct" or "to make right".
What is the Latin root for straight?
Reg- and rect-, which are ultimately from the same source (Proto-Indo-European *reg). The root "reg-" gives us words like "regular", "regimen" and "rule" (the last via French, hence the loss of the 'g'); the root "rect-" gives us "rectify", "direct", "rectilinear" and so forth.
Root word for rectangle?
There is also the root "tang" which could be part of words like rectangle and tangent, but on the search engine I used, rectangle only showed up under "rect" and not "tang".
What is the abbreviation of rectangular?

What does the prefix rect mean?
Straight
What is a Greek root word that means straight or correct?
The Greek root word "ortho-" means straight or correct. This root is commonly found in words such as orthodontist (a dentist who corrects irregularities of the teeth) and orthodox (adhering to traditional or correct beliefs).
Implement a base class Geo and derived from this class Rect a constraint such as any derived classes from Geo must have method to calculate the area.Derive from Rect class Sqr its const take one value?
This is not a question, it is an assignment. class Geo { public: virtual double area (void) const = 0; virtual ~Geo (void) {} // ... }; class Rect : public Geo { private: double m_width; double m_height; public: Rect (double width, double height): m_width (width), m_height (height) {} double area (void) const override { return m_width * m_height; } ~Rect (void) override {}; // ... }; class Sqr : public Rect { public: Sqr (double width): Rect {width, width} {} ~Sqr (void) override {} // ... };
What prefix means straight?
The prefix that means straight is "ortho-".
How did the rectangle get its name?
