A straight line touching a circle is called a tangent. The following is the image of a tangent to a circle with center C and radius AC. The tangent touches the circle at only one point - A.

To draw a perfect circle you will need a drawing compass. To draw a circle you will need a pencil and paper. Starting at the top centre of the paper, place the point of the pencil. Curving around to either the right or the left which ever preferred Guide the pencil all the way around to the starting position making sure that it is symmetrical all the way round. There you have your circle. You may want to use a drawing compass to assist you in drawing a perfect circle. If you do not have a drawing compass you can improvise with a thumb tack and some string. Tie one end of the string to the tack and pin it where you want the centre of your circle to be. Tie the other end to your pencil. Keep the string stretched and move the pencil around the pin to draw a circle. You can change the size of the circle by changing the length of the string.
i beleve they are 4 feet apart
Place a four foot long level on the roof, parallel with the ground. With one end touching the roof and the other end in the air, read the bubble on the level. When the bubble says it is level, then have a second person measure the distance from the end hanging in the air straight down to the roof. Divide the number by 4. (example: with level bubble showing "level"; your helper reads 24 inches on the tape measure-- you divide 24 by 4 = 6" Your roof pitch is 6 /12, or 6 in 12." Every 12 inches of level travel your roof goes up 6 inches.
They each have their place, but on the same style roof, trusses would be stronger.
It could be a caret, which is a mark (‸) made in written or printed matter to show the place where something is to be inserted.
It is called a tangent.
because it nearly touches the artic circle and there is polar winds
6.4cm since the radius of a circle is it's center point to any place on the side. A diameter is the straight line that comes from one point on the side passes through the center point and touches the other side Bottom Line: The diameter is double the radius.
Its a place where someone lives called Tanadak circle in Arkansas, US.
The distance in a straight line from one place on a ripple to the same place on the next ripple is called the wave length.
You will need... A set of compasses (for drawing the circle), and a straight edge. First, draw the circle. Then - put the point of the the compasses on the line. Mark the circle where the pencil crosses it. Place the point on this intersection and repeat the action until you're back at your starting point. Now - using the straight edge, join every alternate point to each other - forming an equilateral triangle.
Generally called an axis. Can also be pole.
light touches it.
A circle is perfectly round, and has one center. An ellipse is like a circle with TWO "centers", and each "center" is called a "focus". The plural of "focus" is "foci". Take a piece of string and tie a loop in each end. Put a pin through the loops, and hold it still in the center of the circle. Place the tip of your pencil at the center of the string, and you can draw a circle by keeping the string taut. Now take TWO pins, and put one pin at each end of the string; place the pins at some short distance apart, and hold them there. Place your pencil and draw, and the shape you draw will be an ellipse. The two pinpoints are the focuses, or foci, of the ellipse. Eccentricity is a measure of how far the ellipse varies from a circle. An ellipse with an eccentricity of zero _IS_ a circle, while an eccentricity of 1.0 is a straight line, with that string stretched out straight. In astronomy, every natural orbit is an ellipse.
The RADIUS. Other nomenclature for a circle are:- Diameter ; Two radii forming a straight line through the circle centre. Chord ; A straight line from one point on the circle to another point on the circle that does NOT pass through the circle centre. Arc ; Part of the circumference. Segment ; An area inside the circle bounded by two radii and an arc. Tangent ' A line just touching the circle's circumference in ONE place. NB The plural of the noun 'Radius' is 'RADII' , not radiuses. 'Radii' is pronounced 'Ray- dee - eye'. NNB 'pi' is the Classical Greek small case letter 'p' , for 'proportion. It is an Irrational number, but for elementary(school) purposes it is given as the approximation '3.14' or '22/7' Being an Irrational number means the decimals are NOT in any regular order and go to infinity. pi ~ 3.141592.....
