The Swimmer’s Shortcut Problem
A swimmer starts at a point on the shore, swims 200 meters due east, then turns and swims 300 meters due north․ To find the shortest distance back to the starting point, the problem forms a right triangle․ Using the Pythagorean Theorem, the straight-line distance can be calculated․ The eastward and northward distances serve as the legs, and the shortcut is the hypotenuse․ The solution involves squaring both distances, summing them, and taking the square root․ The answer is rounded to the nearest tenth and provided in meters for practical application․
The Ladder Against a Wall Scenario
A ladder leaning against a wall forms a right triangle with the ground and the wall․ If the ladder is 12 feet long and placed 5 feet from the wall, the height it reaches can be found using the Pythagorean Theorem․ The ladder serves as the hypotenuse, while the distance from the wall and the height on the wall are the legs․ By calculating the square root of (12² ⎼ 5²), the height is determined to be approximately 11․62 feet․ This problem illustrates a practical application of the theorem in everyday situations․
Calculating the Height of a Rectangular TV
A rectangular plasma TV screen with a width of 40 inches and a diagonal of 52 inches requires calculating its height using the Pythagorean Theorem․ The diagonal serves as the hypotenuse, while the width and height are the legs․ By applying the formula ( c^2 = a^2 + b^2 ), where ( c = 52 ) and ( a = 40 ), the height ( b ) is found by solving ( 52^2 = 40^2 + b^2 )․ This results in ( b = 30 ) inches, providing the TV’s height for proper installation or mounting․
Determining the Perimeter of a Painting
A rectangular painting with a height of 36 cm and a diagonal of 45 cm requires calculating its width and perimeter․ Using the Pythagorean Theorem, where the diagonal is the hypotenuse, the width is found by solving ( 45^2 = 36^2 + b^2 )․ This results in ( b = 27 ) cm for the width․ The perimeter is then calculated as ( 2 * (height + width) ) = ( 2 * (36 + 27) ) = 126 cm, providing the total length of the painting’s frame․
Designing a Bike Path Extension
City planners use the Pythagorean Theorem to design efficient bike paths․ For instance, a path extension might run 35 meters east and 42 meters north․ To find the straight-line distance, calculate the hypotenuse using ( a^2 + b^2 = c^2 )․ Substituting the values, ( 35^2 + 42^2 = c^2 ), yields ( c = 54․4 ) meters․ This calculation ensures the path is direct, saving space and materials, while providing a safe route for cyclists․
How to Answer Pythagorean Word Problems
Read the problem carefully, identify the right triangle, label the sides, apply the Pythagorean Theorem formula (a² + b² = c²), and round the answer to the nearest tenth․
Understanding the Problem and Identifying Variables
Begin by reading the problem thoroughly to grasp the scenario․ Identify the right triangle involved and determine which sides are given or need to be found․ Label the sides as ‘a,’ ‘b,’ or ‘c’ (hypotenuse)․ Drawing a diagram can help visualize the problem and ensure all variables are correctly assigned․ This step is crucial as misidentifying the sides can lead to incorrect calculations․ Always note the units provided to ensure consistency in the final answer․
Applying the Pythagorean Theorem Formula
With the variables identified, plug the known values into the Pythagorean Theorem formula: (a^2 + b^2 = c^2)․ Ensure that ‘c’ represents the hypotenuse․ Perform the calculations step-by-step, squaring the known sides and summing them to find the missing side․ If solving for ‘c,’ take the square root of the sum․ If solving for one of the legs (‘a’ or ‘b’), rearrange the formula accordingly․ Always double-check the arithmetic to avoid errors and ensure accurate results․
Rounding Answers to the Nearest Tenth
After calculating the unknown side using the Pythagorean Theorem, round the answer to one decimal place․ Examine the hundredths digit to determine if it rounds up or stays the same․ For example, 12․34 becomes 12․3, while 12․35 becomes 12․4․ This step ensures precision and practicality, as real-world measurements often require rounded values․ Always check the problem’s instructions to confirm the required decimal places for the final answer․
Presenting Final Answers with Units
Always include appropriate units with your final answers, such as meters, inches, or feet․ For example, write “15 feet” rather than just “15․” This practice enhances clarity and ensures the answer makes sense in the context of the problem․ Properly labeling units also helps in real-world applications, where measurements are essential for accuracy․ Teachers emphasize this step to prepare students for practical scenarios in fields like construction and engineering․
