What is arc and chord?
An arc is part of the circumference of a circle and a chord is a straight line that meets two points of the circumference with the diameter being the largest chord.
How do you construct angle120 degrees with using a compass?
First draw a horizontal straight line a b Put compass point on a (open compass approximately half the length of line a b - note: ensure the compass is not altered throughout the following). Draw an arc that cuts line a b at c. Put compass point on c and draw an arc from a to cut the first arc at d. Draw a straight line through a d to form a 60 degree angle. For a 120 degree angle, put compass point on dand draw an arc from a to cut the first arc at e. Draw a straight line from a through e to give a second angle of 60 degrees: 60 + 60 = 120 degrees.
What is the term for a line that meets a circle or arc at only one point on it's exterior so it will not go through the circle?
a tangent to the circle
How many sides does an arc have?
The same as a straight line.
What is mathimatical radious?
In mathematics, the radius of an arc is a straight line from the centre of curvature of the arc to the arc. In the case of a circle it is the line from the circle's centre to its circumference.
Draw a triangle with equal sides?
Draw a straight line. Set a compass to the length of the line. Scribe an arc from each end of the line so the arcs intersect. Draw straight lines from each end of the original line to the intersection point
How do you draw a parallelogram with right angles?
A parallelogram with right angles is a rectangle.---------------------------------To construct a right angle using a straight edge and a pair of compasses:Draw the first lineExtend the first line beyond the point where the right angle is required (call this point O).With the point of the compasses on the point where the right angle is to be constructed draw a small arc on the straight line either side of point O; call the points where these arcs cross the straight line as A and B.Open the compasses to a larger widthWith the point of the compasses on one of points A and b (say A) draw one arc above the line roughly in the middle between points A and B (above point O).With the point of the compasses on the point of A and B (say B) draw an arc to intersect the last arc just drawn (above point O); call this point CUsing the straight edge, join point O to point C, forming a right angle.rub out the extended bit of the line beyond point O that was used to construct the right angle.
What are the proper steps for constructing an angle bisector?
Suppose you need to bisect angle PQR using only a pair of compasses and a straight edge:Draw an arc with the point of the compass at Q so the arc QP at X and QR at Y.Draw an arc with the point of the compass at X so that the arc is between the arms of the angle and extends to more than halfway across.Without changing the compass setting, draw an arc with the point of the compass at Y so that this arc intersects the previous arc at Z.Using the straight edge, draw the line QZ: this is the bisector of angle PQR.
Curved side 1 straight side and 2 corners?
This is a segment of a circle.The straight line is a chord.The curved line is an arc.
Line from the arc to the center point of a circle?
Radius
What is a chord in geometry?
A straight line connecting two points on the circumference of a circle
In mathematics term what does chord mean?
a straight line joining the ends of an arc
