The cosine rule which is: a2 = b2+c2-2*b*c*cosine A

This is used to find the third side of a triangle when the two other sides are known along with the angle between them.

Used when the triangle is not a right angle.

This is the 'Proof' for congruent triangles.

NB There are other 'proofs' too!!!

They are

SSS = Side, Side, Side

ASA = Angle, side, angle.

but NOT 'AAA'

What does it mean for a side or angle to be included?

The 'included side' is the side between the two given angles. The 'included angle' is the angle between the two given sides.

What is the angle-angle-side rule?

Side-Angle-Side is a rule used in geometry to prove triangles congruent. The rule states that if two sides and the included angle are congruent to two sides and the included angle of a second triangle, the two triangles are congruent. An included angle is an angle created by two sides of a triangle.

What makes a quadrilateral unique?

4 sides and 1 diagonal is given. 3 sides and 2 diagonals are given. 3 angles and measurement of two adjacent angles are given. 3 sides and 2 included angles are given. 4 sides and 1 angle is given.

What is the point that two sides of a polygon have in common?

Any two adjacent sides on a polygon will form an included angle.

What is the difference between angle side angle and angle angle side?

The first is two angles and the included side whereas the second is two sides and the included angle!

How do you find all the angles of a triangle with only one angle available?

it is impossible to do because you need at least 2 angles to tell the other one All unknown sides and angles of a triangle can be found only when one side and two angles, two sides and the included angle, two sides and an angle opposite one of them, or three sides are given. All you will know is that the sum of the other two angels is 180 - (value of known angle).
