The Law of Tangents | Proof & How it works?
It is a relationship between the tangents of two angles and two sides in a triangle. You can easily find out the any one missing variable (value or angle) if the corresponding sides and angles are known.

ATAN2
Returns the arctangent of the specified x- and y- coordinates. The arctangent is the angle from the x-axis to a line containing the origin (0, 0) and a point with coordinates (x_num, y_num). The angle is given in radians between -p and p, excluding -p.

solid contains 12 pentag... | 677.169 | 1 |
What is lattice centering?
Definition. When the unit cell does not reflect the symmetry of the lattice, it is usual in crystallography to refer to a 'conventional', non-primitive, crystallographic basis, ac, bc, cc instead of a primitive basis, a, b, c. This is done by adding lattice nodes at the center of the unit ce... | 677.169 | 1 |

Measurement of a Circle is a treatise that consists of three propositions by Archimedes. This is a short work consisting of three propositions. It is written in the form of a correspondence with Dositheus of Pelusium, who was a student of Conon of Samos. The treatise is only a fraction of what was a longer work. [1] Th... | 677.169 | 1 |
I received this question long time ago from one of my old friends who is mathematician/physicist. He called it the hardest geometry question with "a triangle" and "a circle". I am not sure if he know the answer or not. Here it is.

As shown in the diagram $\angle BAC=90^\circ$. Let $X$ be the foot of the altitude from $A$ to $\overline {BC}$, $\overline{AY}$ be the bisector of $\angle BAC$, and $\overline{AZ}$ be the median of $\triangle ABC$. If $\angle XAY = 16^\circ$, then what is the measure of $\angle AYB$ in degrees? | 677.169 | 1 |
