Any two angles of a triangle determine the third angle. As a result, the side angle angle theorem is equivalent to the angle side angle theorem.
The exterior angle of any polygon, including a tricontakaitrigon, is the angle formed between one side of the polygon and the extension of an adjacent side. The measure of the exterior angle of a regular tricontakaitrigon is 2 degrees, as each interior angle of this polygon measures 178 degrees.
All you really need is the length of any side. The easy way would be to measure the diagonals, but you can also measure each side along with the angle of each corner.
A triangle has three angles and three sides and it is possible for all three angles to be different from each other. Each angle is defined by two of the sides - which form the rays meeting at the angle's vertex. The third side is the "opposite" side. The above statement can be proven (eg by the sine rule) for any triangle.
It is a characteristic of any triangle that the longest side is opposite the largest angle and the shortest side is opposite the smallest angle.

The opposite side of any angle in a triangle is the side that is not part of the angle. The side opposite the right angle is the longest side, called the hypotenuse.
The longest side of the right angles triangle is called the hypotenuse. Divide the length of the side opposite the chosen angle by the length of the hypotenuse. This is the Sine of the angle.

Any triangle has its largest angle opposite the longest side, and the smallest angle opposite the shortest side.
No. Any three consecutive congruent parts (angle-side-angle or side-angle-side) make any two triangles completely congruent.
Extend any straight side of a shape. The angle made by that side with the adjacent side of the shape is an exterior angle. Its value is 180 degrees less the interior angle.
To prove that two or more triangles are similar, you must know either SSS, SAS, AAA or ASA. That is, Side-Side-Side, Side-Angle-Side, Angle-Angle-Angle or Angle-Side-Angle. If the sides are proportionate and the angles are equal in any of these four patterns, then the triangles are similar.
