How do you construct a copy of an angle with a compass?

How to Copy an Angle Using a Compass
  1. Draw a working line, l, with point B on it.
  2. Open your compass to any radius r, andconstructarc (A, r) intersecting the two sides ofangle A at points Sand T.
  3. Construct arc (B, r) intersecting line l at somepointV.
  4. Construct arc (S, ST).
  5. Construct arc (V, ST) intersecting arc (B, r) atpointW.

Just so, how do you construct an angle with a compass?

Constructing a 90º Angle

  1. Step 1: Draw the arm PA.
  2. Step 2: Place the point of the compass at P and draw an arcthatcuts the arm at Q.
  3. Step 3: Place the point of the compass at Q and draw an arcofradius PQ that cuts the arc drawn in Step 2 at R.

Furthermore, how do you copy a line segment with a compass? Start with a line segment PQ that wewillcopy. Mark a point R that will be one endpoint of thenewline segment. Set the compasses' point on thepoint Pof the line segment to be copied. Adjustthecompasses' width to the point Q. The compasses'widthis now equal to the length of the linesegmentPQ.

Similarly one may ask, how do you copy a triangle with a compass?

When you copy a triangle, the idea is to useyourcompass to “measure” the lengths of thethreesides of the given triangle and then makeanothertriangle with sides congruent to the sides of theoriginaltriangle.

What is a 60 degree angle called?

An angle whose measure is more than 0°butless than 90° is called an acuteangle.Angles having magnitudes 30°, 40°,60°are all acute angles.

How do you know if a line segment is congruent?

Congruent segments are simply linesegmentsthat are equal in length. Congruent meansequal. Congruentline segments are usually indicated bydrawing the same amountof little tic lines in the middle ofthe segments,perpendicular to the segments. Weindicate a linesegment by drawing a line over itstwoendpoints.
