I'd say it would be easier to list the ones that aren't, but in actuality it would be impossible to list either. Any molecule that has tetrahedral geometry qualifies, examples, ammonium, methane, ethane, propane...ANY alkane, any quaternary ammonium compound.

What is the bond angle for sif6 2?
179 and 103 degrees source and excellent explanation: http://www.madsci.org/posts/archives/2001-02/983324692.Ch.r.html
Is BF2 a bent shape in chemistry?
No, because in Boron Difluoride, there are 3 groups of electrons around the Boron atom meaning the shape is Trigonal Planar and the bond angles are 120 degrees.
Why does the presence of lone pairs contribute to the polarity of a water molecule?
How do lone pairs around the central atom affect the polarity of the molecule?
What is the idealized bond angles for COCl2?
The outer electrons of As is 5, and there are 3 bonded Cl's. this makes the * electrons for the octet rule to be obeyed. therefore AsCl3 will bond with one lone pair, thus the bond angle will deviate from the ideal tetrahedral angle of 109.50. VSEPR theory predicts that lone-pair bonding pair repusions are stronger than bondonding pair- bonding pair repulsions and the bond angle is predicted to be less than 109.50. the actual bond angle is around 980
What type of bonding around a central would result in a trigonal planar molecule -apex?
3 atoms around a central atom with no lone pairs.
Why Must Measurement of central Angle of a circle Always Be 360 Degrees?
Because angles around a point add up to 360 degrees
Are the sum of the angles at a point 180 degrees?
The total sum of angles around a point are 360 degrees.
What are angles around a point?
360 degrees
Why do you subtract 2 from n to find the sum of interior angles?
This has to do with the way in which the sum of the angles is derived. First you select a point inside the polygon and then join that point to each of the vertices. For a polygon with n sides, this gives rise to n triangles. The sum of the 3 angles of any triangle is 180 degrees. So the sum of the angles of all the triangles is n*180 degrees. Now, the "outer" angles of these triangles correspond to the interior angles of the polygon. But the sum also includes the angles formed arounf the central point. The sum of all the angles around this central point is 360 degrees. This is not part of the sum of the interior angles of the polygon and so must be subtracted. Thus, the interior angles of a polygon sum to n*180 - 360 degrees or 180*(n- 2) degrees.

The intersection of two intersecting line?
Combined angles of 360 degrees around the point of intersection.
Can a square tessellate how?
Yes because angles around a point add up to 360 degrees and a square has corner angles of 90 degrees
What do angles on a cross add up to?
Angles around a point add up to 360 degrees
How many angles of a sphere have?

Does a dot has any angles?
Yes it has 360 degrees around it
Why is it that in a tessellation all of the angles that touch a given point must add up to 360 degrees?
The total angles around a point is 360 degrees. Since there can be no gaps or angles, all of the angles meeting at any vertex must sum to 360 degrees.
