1. Find out the angle a (0 ° ≤ a < 360 °) where the end edges of the following angles coincide, and judge which quadrant the following angles are （1）-1441°（2）1790° 2. Fill in the blanks (1) The set of the first quadrant angles is: (2) The set of angles of the end edge on the coordinate axis is:

1. - 1441 ° = - 360 ° * 5 + 359 ° so the angle that coincides with the end of - 1441 ° is 359 ° which is the fourth quadrant angle;
1790 ° = 360 ° * 4 + 350 ° so the angle that coincides with the end edge of - 1790 ° is 350 ° which is the fourth quadrant angle;
2. The set of the first quadrant angles is: {a | k * 360 ° ≤ a ≤ k * 360 ° + 90 °, K (- Z}
The set of angles of the terminal edge on the coordinate axis is: {a | a = k * 90 ° K (- Z}
Note: '-' is a mathematical sign. If you can't type it, you can only show it like this
