How is senate and house of commons are almost similar?

Answer 1

If you are talking about the house of commons in England. First of all, congress in the US is split into 2 seperate groups, the house of representatives (amount of reps. per state determined by population) and the senate (same amount of reps. per state, 2 each) the parliament on the other hand is separated into the house of lords (the equivalent of the senate) and the house of commons (equivalent to the house of reps.) so the similarity are very few, the senate is the "upper house" and the house of commons is a "lower house". the only similarity is that they both run the government.
