某种产品的商标如图所示，O是线段AC、BD的交点，并且AC＝BD，AB＝CD.小明认为图中的两个三角形全等，他的 不正确 试题分析：根据全等三角形的判定方法可知小明的思考过程不正确，应添加条件∠B=∠C，这样可以根据AAS证得结论，或添加条件∠A=∠D，这样可以根据ASA证得结论. 解：小明的思考过程不正确. 添加的条件为：∠B=∠C（或∠A=∠D） 在△ABO和△DCO中 . 点评：全等三角形的判定和性质是初中数学的重点，贯穿于整个初中数学的学习，是中考中比较常见的知识点，一般难度不大，需熟练掌握. 在动画短片《商标的世界》中一共出现过多少个品牌的商标？ Used as Building * Malibu rum: The first logo appeared in the film * Yoshinoya * Pizza Hut: The Diner * Dairy Queen * Lego * Best Buy * Comfort Inn * K-Mart * Levi"s * Durex * IKEA * Oreo * Home Depot * Unocal Corporation * GMC Truck * S&H Green Stamps * Brands under Choice Hotels o Sleep Inn o Clarion Inn * Wendy"s * Columbia House * Do It Best * Mega Blocks * National Car Rental * Nintendo * Hotwheels * Best Western * Tamiya * EMI * Blockbuster Video * Domino Pizza * Avis * Shoppers Drug Mart * U-Haul * Eveready * Spin * Craftsman * Matchbox * 7-Eleven Used as Facility * Audi: appears as design on highway. * Energizer: the lamp of the lamp post. * ICI: swimming pool * Stop & Shop: the traffic lights * French"s * T-Mobile: telephone poles * Delco Electronics: bottom of T-Mobile telephone poles * Dolby Surround: doors for truck and some building * USA Today: newsbox * Randy"s Donuts * Chrysler: windows * American Cancer Society * Ghostbusters Used as Human Being * Bic mascot: School boys * Fido Dido * Customers at the Diner: o Chief Wahoo o Mr. Peanut o The Pep Boys (Manny, Moe, and Jack) * Green Giant: security at the zoo * Pillsbury Doughboy: the chef at the Diner * Colonel Sanders * Esso Girl * Haribo * Big Boy * Pringles (Julius Pringles) * Ronald McDonald * Michelin: Bibendum (aka "Bib the Michelin Man) * M&M"s * Johnnie Walker: outside KFC * Mr. Clean * AOL Instant Messenger * Minuteman Press: inside KFC * Calgary Cowboys * Foot Locker Used as vehicle or part of vehicle * Cruise America * Cummins: blue light on unmarked patrol car * Mercedes-Benz: The steering wheel of the truck that Ronald MacDonald is driving. * Smiley: Ronald"s gearshift * NSTA: on the school buses * Recycling logo: on the trash truck * DuPont: spinning atop cop cars * Grease 2: Motorcycle * Blaupunkt: radio on the patrol car * On the Eurocopter: o BMW o Cisco Systems Used as Plant * Afri-Cola: Palm trees * USB: cactuses. * Little Trees: red and green evergreens * The Timberland Company: brown trees Used inside the zoo * MGM Lion * Paramount Pictures * Playboy rabbits * Batman (1989 film) * The elephant of Republican Party * The donkey of Democratic Party * The Pumper Nic Hippo called "NIC" * The Lacoste Crocodile ("The French crocodile") * Canadian Natural * WWF * MIKO * Tux (Linux penguin) * E! * Nestlé Purina PetCare * Coca-Cola bottle * Jaguar Cars * Flamingo Las Vegas * McDonald"s Golden Arches * Parental Advisory * Discovery Channel * Oscar Mayer * Australian Airlines * MSN butterflies: also at beginning of movie Used at the KFC fast food stand * Fanta * Diet Dr. Pepper * McCain Foods Limited * Burger King * Nestlé Crunch * Sprite (soft drink) * Yum!
