Describe the composition of an atom.

Hi there,
Atom is made up of electrons,protrons and neutrons.
Nucleus is ,ade of protrons and neutrons which is located in centre of the atom and electrons revolve
around it in specific orbits.
Hope it helps.

Since we are trying to prove if angles rat and qas are equal we first want to look at the three angles that make up the triangles. we already know that lines ar and aq are equal and that lines rs and qs are equal so then we are already two-thrids into proving angles rat and qas are equal. first of all we must know that angles ras and taq are equal since that the lines of both triangles are equal. therefore we now know that angles rat and qas are equal through ssa
