Flashcard 8 - Math Flashcard Set for the PERT
Back
Counter clockwise from top right: Quadrant I, II, III, IV
QI: (+x,+y)
QII: (-x,+y)
QIII: (-x,-y)
QIV: (+x,-y)
Explanation:
Imagine the cartesian plane, with the x and y axes dividing the plane into four parts (each part is called a quadrant). They are named or numbered from I to IV, counting counterclockwise from top right. The coordinates in quadrant Q1 are (+x, +y); in QII are (-x, +y); in QIII are (-x, -y); and in QIV are (+y, -y).
