Can you draw a line on the surface of the sphere?
No, we cannot draw a line on the surface of the sphere, which lies wholly on it.
How do you draw a sphere line?
The Method Start with a circle. Pick a point somewhere inside the circle. Join A and B by a line and extend that line. Draw a line perpendicular to AC. Draw a line starting from D and is parallel to AC. Draw a line starting from E and is parallel to CD. Clean except AB, F.
Can you draw a line on the surface of a sphere which lies wholly on it explain your answer?
Answer: No, we cannot draw a line on the surface of a sphere, which lies wholly on it.
Why it is not possible for a line to have a midpoint?
Midpoint of a line segment Only a line segment can have a midpoint. A line cannot since it goes on indefinitely in both directions, and so has no midpoint. A ray cannot because it has only one end, and hence no midpoint. The midpoint of a line segment can be found using a compass and straightedge.
How many lines can be drawn passing through three collinear points?
(iii) Only one line can be drawn through three collinear points.
What Cannot be drawn on a paper?
A line cannot be drawn on a paper. We can only draw a line segment on a paper. A line extends indefinitely in both directions and therefore we cannot draw a line on a paper. Whereas a line segment is of finite length.
Can a ray be curved?
A line segment corresponds to the shortest distance between two points. Two lines in a plane are said to be parallel if they do not meet. A ray is a portion of line starting at a point and going in one direction endlessly. Any drawing (straight or non-straight) done without lifting the pencil may be called a curve.
What are curved surfaces?
The curved surface is a rounded surface which is not flat. Curved Surface. Flat Surface. An object can have a curved surface all around it. Such objects have only one surface throughout.
How do you measure a polystyrene ball?
Circumference. This is the measurement around the outside of the ball at the widest point. This would be measured with a tape measure, similar to taking a waist measurement.
What are opposite rays?
Two rays are opposite rays, by definition, if. (1) they have the same endpoint, and. (2) their union is a line. The first letter in the name of a ray always refers to the endpoint of the ray. Therefore, has its endpoint at and has its endpoint at .
Do lines and rays have midpoints?
Do rays and lines have a midpoint? Only a line segment can have a midpoint. A line cannot since it goes on indefinitely in both directions, and so has no midpoint. A ray cannot because it has only one end, and hence no midpoint.
Do midpoints create right angles?
By definition of a midpoint, segment AD is congruent to segment BD. Segment DE is parallel to segment AC so angle BDE and angle ADE are right angles. Thus the midpoint of the hypotenuse is equidistance from all three vertices. Triangle ABC is seen in the figure below.
How many lines can be drawn through 18 points on a circle?
→ x = 153 lines (Ans.)Apr 25, 2021.
How many lines can you draw using 3 non-collinear?
Four lines can be drawn through 3 non-collinear points.
Which line can pass through a single point?
Only one line can pass through a single point. There are infinite numbers of lines which pass through two distinct points.
How do you make a sphere hollow on shape?
Best Answers Model the part you want to hollow. Start a thicken and set it to intersect. Set the thickness of the part that you desire. Cross/box-select all of the faces. Use a section plane to verify it is hollowed correctly.
What object is a sphere?
A sphere (from Greek σφαῖρα—sphaira, “globe, ball”) is a geometrical object in three-dimensional space that is the surface of a ball. Like a circle in a two-dimensional space, a sphere is defined mathematically as the set of points that are all at the same distance r from a given point in a three-dimensional space.
Can we draw a line or ray on paper?
We cannot draw a line on paper.
Can we draw a ray on paper?
Answer: Above answer is totally correct!Feb 15, 2019.
Can we draw a complete picture of a line on a paper?
Answer: No, because a line is endless and that is why it’s symbol is : Hope this helps you please mark it as the brainliest and please follow me.
Which curve does not cross itself?
A simple curve is a curve that does not cross itself.
Does a plane have an endpoint?
A ray is a line that only has one defined endpoint and one side that extends endlessly away from the endpoint. A flat surface without edges and boundaries is called a plane. It extends infinitely in two dimensions and is named by three points in the plane that are not on the same line e.g. xyz.
Can a line be a ray?
A ray is a part of a line that has one endpoint and goes on infinitely in only one direction.
Does a sphere have curved surfaces?
a sphere has a single curved surface and no edges or vertices. a cylinder has one curved surface, two curved edges (always circles) and no vertices. • a hemisphere has one curved surface, a flat face and a curved edge (always a circle).
How many curved surfaces has a sphere?
A circle has one flat face. A sphere has no faces and one curved surface.
Can a face be curved?
A face is the part of the shape that has the largest surface area – some can be flat, some can be curved e.g. a cube has 6 flat faces whereas a cylinder has 2 flat faces and 1 curved face.
Why do you need to draw a center line before you draw a circle?
Centerlines indicate a circular feature on a drawing. In 2D, most circular features look exactly the same as features with non-circular geometry. The only way to tell them apart is by adding a centerline, which represents their central axis and confirms their geometry.
What’s the center of a circle called?
The center of a circle is also called the focus of the circle. In general, a focus of a two-dimensional shape is a point that can be used to define.
How can you mark centre of the circle is given without centre?
Then draw perpendicular bisector of both the chords. Then join the end point of any chord to the point of intersection of perpendicular bisector of the chords. Then taking the length of the point of intersection of perpendicular bisector of both chords to the end point of the chords as centre and draw the circle.
