Mention any three similarities between the ideologies of Fascism and Nazism.

(1) Both rejected DEMOCRACY and believed in a one-party state under a single all-powerful leader whose word was law — Mussolini as Il Duce and Hitler as Der Führer. All opposition parties, free speech and a free press were suppressed. (2) Both preached EXTREME NATIONALISM and glorified war and military strength as the path to national greatness, holding that the individual existed for the state and had no rights against it. (3) Both were bitterly OPPOSED TO COMMUNISM and to socialism, which won them the support of industrialists and the middle classes; and both pursued aggressive imperialist expansion to build empires — Italy in Ethiopia, Germany in Austria and Czechoslovakia.

One mark per similarity. The question asks for what the two ideologies SHARED, so avoid anything peculiar to one. The trap to avoid is RACISM and ANTI-SEMITISM: those were distinctively Nazi and were not part of Italian Fascism, so offering them as a similarity loses the mark. The safest three are dictatorship of one leader, extreme nationalism with glorification of war, and hostility to communism.
