Classification of tria

ngles by their sides:

equilateral = 3 sides are equal

isosceles = 2 sides are equal


ne =

no equal side


n of tria

ngles by their a


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

Is a triangle an irregular polygon?

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>

What is the value of the bond angles in COH2?

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.

What is the bond angle Br-P-Br and Cl-P-Br?

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.

What is the Perimeter of a 4 X 6 square?

This is a trick question. A square by definition has four equal sides, therefore it cannot measure 4 x 6. A geometrical figure having four sides, right angles, and measuring 4 x 6 would be called a rectangle, not a square. And it would have a perimeter of 20. <p></p><p> </p>The definition of a square is that all four sides are equal.<div><br></div><div>Therefore your 4x6 is a rectangle, and not a square.</div><div><br></div><div>Perimeter would therefore be</div><div><br></div><div>4+6+4+6= 20.<div></div><div><br></div><div>Total all four sides of the rectangle. </div></div>

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

How do you adjust text in right and numbers in left sides in same page via HTML?

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.
