Shape
Shapes are planes with edges. A plane is a flat surface extending infinitely in width and height. A plane can be parallel to the format containing space, or it can recede or protrude in space to create depth. Shapes have composition with boundaries which separate the space they enclose from what surrounds them.

What do paths of comets, supersonic booms, ancient Grecian
pillars, and natural draft cooling towers have in common? They can
all be modeled by the same type of conic. For instance, when
something moves faster than the speed of sound, a shock wave in the
form of a cone is created. A portion of a conic is formed when th... | 677.169 | 1 |
If both circles had the same radius, X would be located in the center between Ea and Eb. In my case, I used $A = (350 ; 350), B = (150 ; 200), r_1 = 175, r_2 = 125$. X was about X = (226.326 ; 257.245). After thinking about it, I came up with the idea, that X has to be located at (r2/r1)*l.
But $(r_2/r_1) = (125/175) ... | 677.169 | 1 |
In this section I examine a kind of generation of a circumparabola connected with bundles of parallel lines.
I start with an exercise on some line-intersections:

(a) Prove that the shear center of an equal-leg angle (Fig. 1) is at the corner of the angle, and prove that the resultant of the shear flow in the legs of the angle is equal to the total shear force on the section. The shear force acts normal to the axis of symmetry of the cross section. Assume that t \ll b. (b) Deter... | 677.169 | 1 |
Show that a triangle $T$ in ${\bf H}$ is an equilateral triangle

Consider a triangle ABC and the reflexion of points on a bisector AD of angle A say. This transformation
is called isogonal with respect to the bisector AD. The transformation, being a particular reflexion
preserves distances and maps lines to lines. In particular a line AX through A is mapped to a line AX'
through A, ... | 677.169 | 1 |
Law of cosines exercises pdf

The cosine of an acute is positive, whereas the cosine of an obtuse angle is n... | 677.169 | 1 |
Start with an equilateral triangle ABC and the diametral point D of A on its circumcircle. For every line through D consider the intersection points {E, F, G} with sides {BC, AB, AC} correspondingly. Then their fourth harmonic point coincides with the second intersection point H of the line with the circumcircle. And i... | 677.169 | 1 |
