4. 1.Each square design is made up of rectangles of equal size. Each rectangle is twice as long as it is wide. The length of each side of the rectangle is given. Following the pattern, which of the following is possible? A Square made of 18 rectangles has a side length of 24 B Square made of 24 rectangles has side length of 33 C Square made of 28 rectangles has side length of 45 Correct Answer!!!! Numbers make sense, but check the pattern carefully # of rectangles must match the pattern. Not possible! Second, figure out the pattern of the side lengths: 9, 15, 21,… Start at 9 and then count by 6 CONTINUE CLICKING SCREEN FOR HELP AND HINTS 15 cm21 cm 9 cm First, figure out the pattern of the number of rectangles: 4, 8, 12, … Start at 4 and then count by 4 49 815 1221 1627 2033 2439 2845 3251

5. 2. Triangle ABC is shown below. If the length of AC is 29 cm, what is the approximate length of AB? F 27 cm G 36 cm H 21 cm J 26 cm Correct Answer!!!! Use a 2 + b 2 = c 2, not c 2 – a 2 = b 2 Use Pythagorean Theorem, not addition Cannot assume ABC is a right triangle! This is a right triangle! Notice the square. CONTINUE CLICKING SCREEN FOR HELP AND HINTS 12 cm 13 cm B A C This is a Pythagoren Theorem problem. a 2 + b 2 = c 2 Find the missing side of the triangle. Then subtract from 29 to find the resulting length. Use Pythagoren Theorem again to find AB. 24 cm 5 cm Common Mistake: Do not assume ABC is a right triangle. INCORRECT!!
