When Sam drove to the city square and noticed that the lines weren't quite right and a few degrees off like a trapezoid so he might be interested in geometry. Therefore, the final answer is geometry. <hau> Lines da digiri suna da alaƙa da lissafi. Lokacin da Sam ya tafi filin gari kuma ya lura cewa layin ba daidai ba ne kuma wasu digiri kaɗan kamar trapezoid don haka yana iya sha'awar lissafi. Saboda haka, amsar karshe ita ce lissafi.
