This week students will explore Pythagorean Theorem. a2 + b2 = c2 This theorem helps to prove that a triangle is a right triangle and can be used to find the length of any line in the triangle if you know the other two. In the textbook students can use sections 1.5 to 1.7 to develop their understanding Pythagorean theorem. We spent the last week and a half learning about squared numbers and square roots. To be successful students need to remember how to square a number: which is done by multiplying a number by itself. So 4 squared is 42=4 x 4= 16.) Students also need to find the square root of a number for example the square root of 16 is 4.
