8. Name:________________________ Date:____________ 8 Chapter 11 Lesson 7 Pythagorean Theorem Standard Remember Algebra 1 2.0 Understand and use taking a root. A right triangle has a right angle in it ( 90 degrees and looks like a corner. The longest side of a triangle is called the hypotenuse. leg hypotenuse leg The Pythagorean Theorem In any right triangle, if a and b are the lengths of the legs and c is the length of the hypotenuse, then

9. Name:________________________ Date:____________ 9 Chapter 11 Lesson 7 Pythagorean Theorem The sum of the legs squared equals the hypotenuse squared. If we know the length of two sides of a right triangle then we can figure out the third. Example 1: 4 c 5 a = 4, b = 5 so Example 2: 1 b so
