Students identify parallel lines in real objects, count the 8 lines of symmetry in an octagonal stop sign, and find symmetry lines in the letter T. Part B has five fill-in-the-blank problems about butterfly symmetry, parallel lines in the letter E, and the number of symmetry lines in a plus sign.
Real-world symmetry questions in signs, letters, and nature connect abstract geometric concepts to patterns students encounter every day.
