Question

p is a point which is equidistant from two line L and M intersection at point A .psove that the line A bisecls the angle between them
​

Answer 1

Answer:

You are given that lines l and m intersect each other at A.

Let PB is perpendicular on l and

PC⊥m. It is given that PB=PC.

You need to show that ∠PAB=∠PAC.

Let us consider △PAB and △PAC. In these two triangles,

PB=PC (Given)

∠PBA=∠PCA=90  

∘

 (Given)

PA=PA (Common side)

So, △PAB≅△PAC (RHS rule)

So, ∠PAB=∠PAC(CPCT)

Answer:

One group of these derivatives is composed of salts containing the phosphate ion (PO43−), the hydrogen phosphate ion (HPO42−), or the dihydrogen phosphate ion (H2PO4−), and positively charged ions such as those of sodium or calcium; a second group is composed of esters, in which the hydrogen atoms of phosphoric acid .
