1-53. Sketch each triangle if possible. If not possible, explain why not. Use the vocabulary in the Math Notes box in this lesson to help you if you need it. a. Right isosceles triangles b. Right obtuse triangles c. Scalene equilateral triangles d. Acute scalene triangles 1-54. Copy the Venn diagram below on your paper. Then show where each person described should be represented in the diagram. If a portion of the Venn diagram remains empty, describe the qualities a person would need to belong there. a. Carol: “I rarely study and enjoy braiding my long hair.” b. Bob: “I never do homework and have a crew cut.” c. Pedro: “I love joining after school study teams to prepare for tests and I like being bald!” d. Toby: “I really love playing in my heavy metal band, but I don’t have much time for it since I enrolled at MIT. My mom really wishes that I would just cut my long, messy hair.” 1-57. Camille loves guessing games. She is going to tell you a fact about her shape to see if you can guess what it is. a. “My triangle has only one line of symmetry. What is it?” b. “My triangle has three lines of symmetry. What is it?” c. “My quadrilateral has no lines of symmetry but it does have rotation symmetry. What is it?” (The hexagon at right has rotation symmetry, because a 120º, 240º, or 360º rotation, clockwise or counterclockwise about the center point C, maps the hexagon back on to itself.)
