This scene in Harry Potter and the Sorcerer's Stone takes place at the Dursley's home. At this moment, Harry is walking down the hall to go get the mail from the letterbox, after being ordered to by Mr. Dursley. One of the designs on the staircase is shaped like a right triangle.
"Harry dodged the Smelting stick and went to get the mail. Three things lay on the doormat: a a postcard from Uncle Vernon's sister Marge, who was vacationing on the Isle of Wight, a brown envelope that looked like a bill, and — a letter for Harry." -Harry Potter and the Sorcerer's Stone, Page 34

This scene in Harry Potter and the Prisoner of Azkaban takes place in the Dursley's house. At this moment, they are having dinner with Aunt Marge, which is being served by Harry. The entryway to this part of the Dursley's home has a design on top of the doors where the right triangle is located.
"At last, at long last, the final evening of Marge's stay arrived. Aunt Petunia cooked a fancy dinner and Uncle Vernon uncorked several bottles of wine. They got all the way through the soup and the salmon without a single mention of Harry's faults; during the lemon meringue pie, Uncle Vernon bored them all with a long talk about Grunnings, his drill-making company; then Aunt Petunia made coffee and Uncle Vernon brought out a bottle of brandy.
