What is the normal line for in ray diagrams?
The normal line divides the angle between the incident ray and the reflected ray into two equal angles.
Can a ray be a line segment?
No. A ray is infinite on one side and ends at a point at the other. A line segment ends in two points. A ray can contain a line segment, as the distance between any two given points on the ray is a line segment.
What is the line of symmetry of an angle?
the distance from a point on either ray of the angle that is equidistance from the axis of symmetry is the line of symmetry. the line of symmetry dives the angle in half.
What is an open half line?
A line which has one end, but stretches off to infinity is called a ray. If we want to show an interval such as [2,infinity) which means all the numbers between two an infinity including two, we put a close dot at two and draw a ray going to the right. Similarly for (negative infinity, 2] we draw the closed dot at 2 but this time the ray goes to the left. Now if we draw an open circle, or a the out line of a dot this mean the interval (2,infinity) where we are considering all the numbers very close to two but not two itself This is an open half line and it represents an open interval.
What is a line that has a beginning but no end?
A ray.
What is the difference between a line segment and a ray?
a ray continues on and on but a line segment stops
What is difference between a line and a ray?
a line is two rays put together
What is an difference between a ray and line in math?
a line has a dot on each end and a ray only has one dot and an arrow, it keeps on going.
A line that has only one endpoint?
A ray = A half-line
Is a ray half a line?
no
What is the difference between a line and a ray How do you show a ray in writing?
A line extends infinitely in both directions, a ray in only one. A ray can be shown by drawing a small arrow above the name of the ray, with the arrow pointing in the direction of the ray.
What is the different between a ray and a half line?
A ray starts at a point and extends forever in ONE direction. A line starts at a point and extends forever in TWO directions.
What is the difference between normal ray and the normal?
i think that normal is a line segment and normal ray is a line with an arrow head like vector to point in a certain direction....
Is ray different from segment?
A ray is different from a segement because a ray is half of a line and does not end in one side only but the segement it is half of a line that ends.
How many endpoints does a half-line have?
ray
What is the difference between a ray line and a line segment and a line?
A ray has a single start point, and goes on infinitely in one direction. A line segment has two end points and is finite. A line has no end points and goes on infinitely in two directions.
What is the difference between a line and a line segment and aray?
line: it goes on for infinity. <---------> line segment: has 2 endpoints, does not continue. -------- ray: starts at one point, then goes on for infinity. --------->
