How many lines can be drawn to 18 points on a circle?
→ x = 153 lines (Ans.)
How many lines can be drawn in a circle?
Since there are an infinite number of lines through the center, the circle has an infinite number of lines of symmetry.
How many lines can be drawn from 10 points in a circle?
= 10C2 = 10*9/2 = 45 chords.
How many lines can 6 points on a circle have?
15 lines
Therefore, we can draw 15 lines from the 6 points lying on a circle.
How many can be drawn through 21 points on a circle?
210 chords
Therefore, the number of chords that can be formed using the 21 points lying on the circle is 210 chords.
How many lines can be drawn between 20 points?
2 points are required for a line , so from 20 points total no. of lines are 20C2.
How many triangles can be drawn through 12 points on a circle?
Therefore, 120 triangles can be formed.
What does a circle with a dot in the middle mean?
The circled dot, circumpunct, or circle with a point at its centre is an ancient symbol. It can represent: Solar system. Solar symbol used to represent the Sun. The sun / Gold (Alchemical symbols)
How many regions does a circle have with 4 points?
8 regions
Then we might notice that 8 regions can be formed by chords connecting 4 points on a circle and 16 regions can be formed by chords connecting 5 points on a circle—ah, life looks good here!
How many lines are two points?
one line
(b) Only one line can pass through two given points. A point in geometry is a location.
How many courts can be drawn through 12 points on a circle?
The answer is 66 .
How many dots are there in the quiz?
The quiz consists of 10 different arrangements of shapes with one dot placed in each of them. Can you tell which dots are perfectly centered within the shapes and which are slightly off?
Is the dot in the center of the circle?
ANSWER: No, the dot is not in the center of the circle. It’s not centered. The dot is slightly below and left of center. 3. Is the dot in the center of the square?
How many chords can be determined by a circle with 7 points?
This would lead us to expect the number of chords determined by a circle with 6 points on it would be 10 + 5, or 15, and we would also then expect the number of chords determined by a circle with 7 points on it to be 15 + 6, or 21. A quick look at the diagram below will show us that we are correct in our assumption.
How many regions can a circle with 6 points have?
If we go along with our idea mentioned above, we would expect the maximum number of regions for a circle with six points on it to be 32, but refer to the figure below to see that it is not so. So our first idea might be shot now, but that does not mean that there is not some pattern to it.
