Classification of tria

ngles by their sides:

equilateral = 3 sides are equal

isosceles = 2 sides are equal

scale

ne =

no equal side

Classificatio

n of tria

ngles by their a

ngles:

acute = the 3 a

ngles are less less tha

n 90 degrees

right = it has a

n a

ngle which is 90 degrees

obtuse = it has a

n a

ngle which is more tha

n 90 degrees

All sides must be equal in length and all angles must br equal in size

It depends on the length of the sides and the degree of the angles. If L1=L2=L3, and <a=<b=<c, then it is a regular polygon. Can you read algebraic expressions? If you can't, get someone who can. <br>

This is a trick question. A square by definition has four equal sides, therefore it cannot measure 4 x 6.

The bond angle in COH2 is approximately 90 degrees. Each hydrogen atom is located at the corners of a triangle around the central oxygen atom, resulting in a bent molecular geometry.

The problem with this question is that bond angles will depend on which molecules are being referred to.PBr2 and PClBr are not compounds they are transient molecules.In VSEPR terms they are odd electron molecules with 7 electrons in the outer shell they will be bent. I do not believe that bond angles are known.P2Cl4 - the molecule is trans Cl2P-PCl2- I don't know if bond angles have been determinedP2Br4 is not well characterised.In PBr3 the Br-P-Br angle is 101 oIn PBr5 the solid is actually PBr4+ Br- PBr4+ is tetrahdral with 109.5o angleMixed halides PClBr2 and PCl2Br are known. I can't find the bond angles for these. VSEPR predicts a trigonal pyramidal shape - bearing in mind that the bond angles in PBr3 and PCl3 are 100 o and 101 o respectively I think a prediction of around 100-101 o would be reasonable for the Cl-P-Br angle.

Yes, it is symmetric. The C is at the center, surrounded by 4 Br atoms at equal angles.

That's what CSS is for.Example:---/* CSS rules for formatting */.number { text-align: right; }.label { text-align: left;}a label123---You set the 'class=...' attribute on the tags to refer to a formatting rule, and put the formatting rules in tags in the header or in a separate file.See related link on CSS.

Correct HTML tag for inserting a line break? you can use <br/>

The smallest radius from I Br Br I would be the bromine atom since it is closer to the central iodine atom compared to the outer iodine atom.
