What is Group A called in periodic table?
In the older periodic table, each group was divided into A & B sub-groups. The only problem with that was that there were two different conventions about which elements were labelled "A" and which were labelled "B". Groups 1 & 2 were clearly 'A' (elements like sodium and calcium) and 11 & 12 were clearly 'B' (elements like copper and zinc). But groups 3 through 10 were labelled 'A' in one convention and 'B' in another, and the opposite labels were used for groups 13 through 18.With the second labelling convention, groups labelled 'A' were known as 'main group elements', and groups labelled 'B' were 'transition metals', and that is still the case.Thus in the newer IUPAC scheme, groups 1, 2, and 13 through 18 are called 'main group elements'.

In the cell address C4 what does C signify?
The column. The columns are labelled alphabetically, e.g. "A" is column 1, "B" is column 2, "C" is column 3 and so on. The 27th column is labelled "AA", the 28th "AB" etc.
How do you prove the sine rule?
Imagine a random triangle ABC. It will make it easier if you draw it with angle C at the top. The opposite side of angle A is labelled a, the opposite side of angle B is labelled b and the opposite side of angle C is labelled c. Draw the altitude (height) from angle C so that it is perpendicular (at 90 degrees) to side c. Looking at this triangle, find expressions for the sines of angles A and B: sinA = h/b sinB = h/a Rearrange these two equations in terms of h: h = bsinA h = asinB As h = h, these equations can be set equal to each other and simplified to find the sine rule: bsinA = asinB sinA/a = sinB/b If you expand on this way of working, you can also find that sinA/a = sinB/b = sinC/c. You have now proven the sine rule for all triangles!
How many pairs of congruent sides does a square have?
Six. If the sides are labelled a, b, c and d then the congruent pairs are: ab, ac, ad, bc, bd and cd

What are the angles of a diamond shape?
If the angles are labelled A, B, C and D with A and C as the "pointier" ones, then C=A, B=D=180-A where A is any angle between 0 and 90 degrees. Clearly, A cannot be 0 degrees and if A is 90 degrees, the diamond (rhombus) becomes a square.
How do you name the side that is opposite the angle?
If your are referring to a triangle, then the vertices (angles) are identified using capital letters. So, for example, you can have a triangle ABC.The sides opposite to each angle are labelled in lower case.a is opposite ∠A, b is opposite ∠B, and side c is opposite ∠C
