How do you know what angles in a triangle are worth using algebra?

If the triangle is equilangular, then all angles are 60 degrees:
180/3 = 60
If the measures of two angles are given, you can discover the 3rd one by subtracting the sum of the two angles from 180.

What makes a product special?
In math, like algebra and calculus, a product is special when it is very common and worth knowing.Some examples area:(x + y) = ax + ay (Distibutive Law)(x + y)(x − y) = x2 − y2 (Difference of 2 squares)(x + y)2 = x2 + 2xy + y2 (Square of a sum)(x − y)2 = x2 − 2xy + y2 (Square of a difference)
If a collection of dimes is arranged in a triangular array with 14 coins in the base row13 in the next 12 in the next and so forth. Find the value of the collection.?
If there are 14 rows in the triangle, then there are 14*(14-1)/2 coins in the arrangement, i.e. 91 dimes. To find the value of the collection, simply multiply by the value of a dime. I believe this is 10 cents, so the coins are worth 910 cents, or $9.10.

What figure has all equal sides and all angles have equal?
The only shape that always has equal sides and equal angles is the square.Other shapes can have equal sides and angles (like a triangle or octagon), but they are not by definition equilateral.--------I think it is worth noting that any regular polygon satisfies the definition. Conversely, as you point out, you have to explicitly specify that it is regular.
What ate the properties of a triangle?
SideSide of a triangle is a line segment that connects two vertices. Triangle has three sides, it is denoted by a, b, and c in the figure below.VertexVertex is the point of intersection of two sides of triangle. The three vertices of the triangle are denoted by A, B, and C in the figure below. Notice that the opposite of vertex A is side a, opposite to vertex B is side B, and opposite to vertex C is side c.Included Angle or Vertex AngleIncluded angle is the angle subtended by two sides at the vertex of the triangle. It is also called vertex angle. For convenience, each included angle has the same notation to that of the vertex, ie. angle A is the included angle at vertex A, and so on. The sum of the included angles of the triangle is always equal to 180°.Altitude, h Altitude is a line from vertex perpendicular to the opposite side. The altitudes of the triangle will intersect at a common point called orthocenter.If sides a, b, and c are known, solve one of the angles using Cosine Law then solve the altitude of the triangle by functions of a right triangle. If the area of the triangle At is known, the following formulas are useful in solving for the altitudes..BaseThe base of the triangle is relative to which altitude is being considered. Figure below shows the bases of the triangle and its corresponding altitude.If hA is taken as altitude then side a is the baseIf hB is taken as altitude then side b is the baseIf hC is taken as altitude then side c is the baseMedian, mMedian of the triangle is a line from vertex to the midpoint of the opposite side. A triangle has three medians, and these three will intersect at the centroid. The figure below shows the median through A denoted by mA.Given three sides of the triangle, the median can be solved by two steps.Solve for one included angle, say angle C, using Cosine Law. From the figure above, solve for C in triangle ABC.Using triangle ADC, determine the median through A by Cosine Law.The formulas below, though not recommended, can be used to solve for the length of the medians.Where mA, mB, and mC are medians through A, B, and C, respectively.Angle BisectorAngle bisector of a triangle is a line that divides one included angle into two equal angles. It is drawn from vertex to the opposite side of the triangle. Since there are three included angles of the triangle, there are also three angle bisectors, and these three will intersect at the incenter. The figure shown below is the bisector of angle A, its length from vertex A to side a is denoted as bA.The length of angle bisectors is given by the following formulas:where called the semi-perimeter and bA, bB, and bC are bisectors of angles A, B, and C, respectively. The given formulas are not worth memorizing for if you are given three sides, you can easily solve the length of angle bisectors by using the Cosine and Sine Laws.Perpendicular BisectorPerpendicular bisector of the triangle is a perpendicular line that crosses through midpoint of the side of the triangle. The three perpendicular bisectors are worth noting for it intersects at the center of the circumscribing circle of the triangle. The point of intersection is called the circumcenter. The figure below shows the perpendicular bisector through side b.Source: MATHalino

Explain why the decagons angles equal 1440 degrees?
Here is one way to prove it. It is easier if the decagon is convex but the proof is valid even if not.Take any point P in the plane. Again, it is easier if this point is inside the decagon but the proof is valid even if it is not.Join all the vertices of the decagon to this point. So now you have ten triangles with a common vertex P.The angles of these ten triangles form the internal angles of the decagon plus all the angles around P.So the sum of the internal angles of the decagon is equal to the sum of the internal angles of all ten triangles with P as their common vertex minus the 360 degrees worth of angles at P itself.The sum of the interior angles of each triangle is 180 degrees so the sum of ten triangles with common vertex P is 180*10 = 1800 degrees.So the internal angles of the decagon add to 1800 - 360 = 1440 degrees.
What is a polygon with 4 congruent sides and four right angles?
A square. right angles are 90 degrees and in order to have a square you must have 360 degrees worth of angles. 90x4 is 360 and congruent sides means that they are all the same.
