This section of the trifold should follow the class/small group discussion and answer students' inquiries such as, "Does this work with any triangle or only triangles with side lengths of 3, 4, 5?" stream
you square a (3^2=9=a) and b (4^2=16=b) and add the 2 values (9+16=25) to get to c. To complete the question, you have to square root c's value (square root of 25=5) because the formula says c^2 and not just c. Once you have done that, you can check your answer by squaring a,b and c to see if you have added and divided (Square-rooted) correctly. C. (1, 20), (2, 23), (9, 26) Explanation: Let a = 11, b = 60 and c= 61 simplifying radicals that you will bump into a lot while After rounding to nearest tenth, value of A = 22.6ft, Question 9.
