Autumn (also known as fall in North American English) is one of the four temperate seasons. Autumn marks the transition from summer usually in September (northern hemisphere) or March (Southern Hemisphere) when the arrival of night becomes noticeably earlier. In the northern hemisphere, the meteorological start of autumn is on 1 September and it ends on 30 November;[1] in the southern hemisphere it starts on 1 March and ends on 31 May. The astronomical start of autumn is on 22 September and ends on 20 December in the northern hemisphere, and 20 March and 21 June in the southern hemisphere. Autumn starts on or around 7 August and ends on about 6 November in solar term. Beware of baboons

What pair of slopes could represent perpendicular lines?
Negative reciprocal slopes always represent perpendicular lines.
How can you know when a line is perpendicular?
They are perpendicular if the product of their slopes is -1.
What must be true about the slopes of 2 perpendicular lines?
The slopes of two perpendicular lines are negative inverses of each other. In other words, the two slopes when multiplied together equal -1.
What is the product of the slopes of perpendicular lines?
It is always -1.
When is the product of the slopes of two perpendicular lines not equal to -1?
When the perpendicular lines are horizontal and vertical.
How do you determine if a triangle has a right angle by multiplying slopes?
Well, when the slopes of the perpendicular sides of the right triangle are mutiplied, the result should be -1.
If two lines are their slopes are negative reciprocals?
If the lines are perpendicular, their slopes are negative reciprocals.If the lines are perpendicular, their slopes are negative reciprocals.If the lines are perpendicular, their slopes are negative reciprocals.If the lines are perpendicular, their slopes are negative reciprocals.
What are the slopes of perpendicular lines called?
Slopes of line perpendicular to the x-axis are undefined.
Would perpendicular lines have negative or positive slopes?
I believe they have Negative Slopes as stated by my Geometry Book. "Perpendicular Lines Have Slopes Which Are Negative ___"
What pair of slopes could represent perpendicular lines?
Negative reciprocal slopes always represent perpendicular lines.
How can you know when a line is perpendicular?
They are perpendicular if the product of their slopes is -1.
How do parallel and perpendicular slopes compare or their y intercept?
There is no relationship between the slopes of parallel or perpendicular lines and their y-intercepts.
Do Perpendicular lines have opposite reciprocal slopes?
Actually it IS. perpendicular lines have opposite reciprocal slopes and parallel lines have the same slope.
How do you calculate parallel and perpendicular lines in a given plane?
Take any two lines and look at their slopes. -- If the slopes are equal, then the lines are parallel. -- If the product of the slopes is -1, then the lines are perpendicular.
What must be true about the slopes of 2 perpendicular lines?
The slopes of two perpendicular lines are negative inverses of each other. In other words, the two slopes when multiplied together equal -1.
Do two lines that have slopes of 1 and -1 are perpendicular?

How do you use slope to determine if two lines are perpendicular?
You have to know the slopes of both lines. -- Take the two slopes. -- The lines are perpendicular if (one slope) = -1/(the other slope), or the product of the slopes equals to -1.
