Determine the range of slopes for line passing through point such that does not intersect the line segment connecting points and .
Solution
To determine the range of slopes for line that does not intersect with the line segment AB, we first need to calculate the slopes of line segments PA and PB.
The slope of PA, denoted as , can be calculated using the formula for the slope between two points, .
Similarly, for line segment PB:
Now, we know that the slopes of lines with a 135° inclination angle and a 45° inclination angle are and , respectively.
Since the line should not intersect the line segment AB, its slope must satisfy or . This is because the slopes between these values would mean the line would intersect with segment AB at some point.
Therefore, the slope of line must be greater than or less than , and as a result, the inclination angle range for line is between 45° and 135°, not inclusive.
Hence, the range of slopes for line is translated into the range of inclination angles as .
