Quarter of a circle or circumference crossword

Crossword puzzles have long served as a well liked pastime - they give the brain a workout and yield a clear sense of victory once the last blank is filled. The word “quadrant” suits the puzzle clue because it names one of the four equal parts that split a circle. Quadrants matter in both mathematics plus geometry. On a coordinate plane they tell where a point sits - each quadrant holds its own pair of positive or negative x and y values. Knowing which quadrant a point occupies helps when you deal with circles, angles or any other geometric figure. Apart from their practical use, quadrants carry cultural weight. Graphic artists but also web designers often cut a canvas or screen into four parts to keep the picture balanced. You will find this four part grid in old master paintings and in the layout of a modern home page alike. As you keep solving crosswords as well as look further into mathematics and geometry, the idea of the quadrant will stay useful. Spotting it or putting it to work will not only help you finish crossword grids but will also let you see the steady patterns that run through the world around you.
