How do lone pairs around the central atom affect the polarity of the molecule?
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
The bond angles between two N-H bonds in ammonia are close to the bond angles characteristic of a tetrahedron, but the molecule as a whole is not a tetrahedron because one of the four bonds to a central atom found in an actual tetrahedral molecule is missing; there are only three hydrogen atoms bound to a central nitrogen atom in ammonia. In an ammonium ion, however, the tetrahedron is complete.
The approximate bond angles in CHClO is 120 degrees.
If it is non polar, the bond angles are as follows:I-P-I bond angles: 120ºBr-P-Br bond angles: 180ºI-P-Br bond angles: 90º
"How are straight angles different from right angles?" Is this a statement?

Probably angles and shapes.
When two angles have common vertex and side but do not overlap, they are said to be adjacent angles. Some real examples are intersection of two roads, hands of a clock etc.
real life example of exterior angles
ANY two angles that total 90o, eg the "other" angles in a right-angled triangle.

Table
There is no specific collective noun for angles; an appropriate collective noun is used based on the circumstances. Some examples are a row of angles, a series of angles, a tangle of angles, etc.

No there are different angle such as right angles, obtuse angles, and acute angles.
With three different angles in the corners: Scalene With one different angles in a corner: Isosceles With all the same angles: Equilateral
