Line art drawing of parallel lines and curves.
In geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. By extension, a line and a plane, or two planes, in three-dimensional Euclidean space that do not share a point are said to be parallel. However, two lines in three-dimensional space which do not meet must be in a common plane to be considered parallel; otherwise they are called skew lines. Parallel planes are planes in the same three-dimensional space that never meet.
Parallel lines are the subject of Euclid's parallel postulate.[1] Parallelism is primarily a property of affine geometries and Euclidean geometry is a special instance of this type of geometry. In some other geometries, such as hyperbolic geometry, lines can have analogous properties that are referred to as parallelism.
(0,2.5)(4,2.5)...u will notice that the y's are the same.....that means this is a horizontal line and y will always be 2.5.
so u want a perpendicular line...going through (3,-1)...a perpendicular line would be a vertical line...and a vertical line is represented by x = a number...so look at ur points (3,-1)....what number is in the x spot ? It is 3.....so ur perpendicular line is : x = 3
Answer:
No
Step-by-step explanation:
For it to be a right triangle it would have to be 90 degrees for one side
5/6 of 300 is 250 people that completed the course.
the radius of the distance between the middle point of the circle and the outside, we have the diameter which is 6 so the <u>radius will be 3</u>
slant height is
h is 4.7 and r is 3
