Straight Angle vs. LineDate: 09/07/97 at 11:58:49 From: Andrew Subject: Geometry angle question My question is simple. Why is a straight angle (line) not considered an angle? Thanks a lot. Andrew Date: 09/13/97 at 21:09:47 From: Doctor Mike Subject: Re: Geometry angle question Hi Andrew, First of all, there is a difference between a line and a straight angle. A line is a piece of geometry, whereas an angle is a measure of how TWO lines come together. I like to visualize a straight angle as 2 lines going out from the same point, like ... <----------------------*---------------------> The point is the "*" and the lines go to the left and to the right. The straight angle (180 degrees) is a measure of how those 2 lines come together. So, a line is not an angle, BUT a straight angle is a fine angle. I hope this helps. -Doctor Mike, The Math Forum Check out our web site! http://mathforum.org/dr.math/ |
