The point (4,-3) is rotated 180 degrees around the origin. What are the new coordinates? A. (-4,3) B. (4,3) C. (-3,4) D. (3,-4) 相关知识点: 试题来源: 解析 A。绕原点旋转 180 度,横纵坐标都变为原来的相反数。所以(4,-3)旋转 180 度后的坐标是(-4,3)。反馈 收藏
Step 1:Label all vertices of the shape with their coordinates, and also label the coordinates of any named points on the shape. Step 2:Rotate each point from step 1 about the origin with the specified number of degrees in the specified direction and label the rotated coordinates: ...

rad:A radian is the length of a circle’s diameter around the shape’s arc. One radian is180deg, or 1/2 of a full circle. One full circle is 2π radians, which is equal to6.2832rador360deg. turn:One turn is one full circle. So, halfway around a circle is equal to.5turn, or...
Azimuth/bearing- This is the angle measured in degrees, in a clockwise direction from the north line. Distance- This is the distance in which points will be drawn. Distance from origin to the first point- In some instances you may only be interested in distances away from the point of ori...
I first use the translate method to move the 0,0 origin to the center of the canvas. Each time I redraw the canvas, I rotate the object by 1 degree. The rotate method accepts radians only, so I convert degrees with the formula radians = (degrees * Math.PI)/180; I substitute a 1...
Eight array antennas, each of which is arranged in a manner similar to that of the array antennas of the application integrated circuit, are formed at intervals of 45 degrees around a rotation axis on an imaging process integrated circuit of a movable housing. A controller selects one of the...
