The root word Rect is from the Latin word rectus meaning right. thats why you have words like rectangle and rectify.
RECT
From its right angle. right angle --> rect angle.
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.

All four of the angles of a rectangle (and of squares) are right angles.(Its name comes from this : rect-angle.)
Rectify is derived from the Latin "rectus", meaning "straight". Hence rectify means "to straighten" or by extension "to correct" or "to make right".
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.
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".
RECT
Straight
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).
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 {} // ... };
The prefix that means straight is "ortho-".
From its right angle. right angle --> rect angle.
