Answer to: Prove: In a plane, if two lines are parallel to a third line, then the two lines are parallel to each other. By signing up, you'll get...
34. If two lines are parallel to each other, they are both at a right angle.相关知识点: 试题来源: 解析 两条平行线是在同一平面内永不相交的直线。直角是角度为 90 度的角。题干说两条平行线彼此成直角,这与平行线的定义相矛盾。因此,该陈述是错误的。 1. 定义平行线: 平行线是在同一平面内永...
If a pair of parallel lines is intersected by a transversal, and the measure of one alternate interior angle is 55 degrees, what is the measure of the other alternate interior angle? A. 市关已单际市关已单际55 degrees市关已单际市关已单际 B. 交多支形这观水强成交多支形这观水强成125...
The problem includes checking if the three given straight lines are concurrent or not. If all three lines in a plane pass through the same point, they are said to be concurrent. They must intersect with each other exactly at one point to be concurrent. The three concurrent lines are ...
