WebThis is because up until 90 degrees (or pi/2 radians) the circle is in quadrant 1 at the right angle when it reaches the y axis y is still positive, but now x is 0 quadrant 2 has x negative now, since it is on the left of the y axis. if it's easier you can remember x = 1 is on the right of the y axis, and x = -1 is on the left. WebSep 27, 2024 · The Pythagorean Theorem. If a and b are the lengths of the legs of a right triangle and c is the length of the hypotenuse, then the sum of the squares of the lengths of the legs is equal to the square of the length of the hypotenuse. This relationship is represented by the formula: (2.4.1) a 2 + b 2 = c 2. In the box above, you may have …
