can we draw a angle of 140 degree using a pair of compass? 

please sent the answer soon !!!!!

 Draw a perpendicular bisector of XY whose length is 10.3cm

a).take any point p on the bisector.examine PX=PY

b).if M IS THE MID POINT  OF XY what caan you say about the lengths  MX and MY.

What are perpendicular lines????

What is the difference between a perpendicular and a perpendicular bisector? 

Draw any  angle  with vertex  o.  take a point  a on  one  of  its arms  and B  on. another such  that  OA=OB.  Draw  the  perpendicular  bisectors of  OA and  OB.   Let  them  meet  atP.  Is   PA=PB?

can  we  draw  a  perpendicular  line  without  using  a  compass ?

what are perpendicular lines

 Can we draw a perpendicular bisector without drawing a circle?

Is the first two videos are about how to construct a 90 degree angle ?

For drawing a perpendicular line from a point outside the line can we do it in the following fashion

Draw line L. Take a point P outside it. Draw an arc from P cutting line AB. Then approaching differently take a distance of more than half of AB and draw two arcs in the same side as P (my son did it this way in his test). This is different from your approach since it doesnt take the same radius as the arc from P cutting AB. Even here when you connect P to the connecting point of two arcs and extend it to the line, you get a perpendicular line from P to line L. Isnt this correct?

1.  Why was arc important in the constructing of an angle?...
2.  Why perpendicular line are in right angle ?....
3. What is the use of angle ?... hope you can make me understand >>>>>>

in the last three videos can't we just draw a line using a ruler and pencil.instead doing of the stylish way?

can you copy an angle by using a compassesand a ruler

What is the difference between perpendicular lines and perpendicular bictors.

I have a doubt in constructing a perpendicular bisector.Now,how do we construct a perpendicular bisector if there is a fixed length say AB=7cm? 

what is perpendicular bisector ?????????

what is ment by perpendicular bisector ?

what is the mean of adjacsent angles/sides?

 how did you use a set square in the second video

it has a lot of confution in that and what is the perpendicular bisect ?

 why do we need to draw arcs from 2 points before making perpendicular line

in the above vedio they have drawn 2 circles to form the perpendicular bisector of the line segment

we can directely draw 2 acs

one on the upper side while the other lower side at both the points isin't it?

 IN THE SECOND VIDEO ITS GIVEN TO BE DONE WITH RULER AND COMPASS BUT IN THE VIDEO ITS SHOWN WITH RULER AND SET-SQUARE

one video is not coming

can u check it , please

do u have to make the arc down for making a perpendicular to a line

CAN WE MAKE 2 ARCS INTERSECTING EACH OTHER ,INSTEAD OF CIRCLES

 in this video the  intersecting circles  that are made also has a specific name or not?

 I  could  not  undrstand  the  meaning  of  suitable  here 

why to use the rounder , we can use a scale directly .....?

Is there an other way to construct a perpendicular bisector

CAN WE PLACE SET SQUARE ANYWHERE ON LINE AB?

 What is the symbol used fir perpendiculars ?

Why Is Arks In Some Video's Are So Important

what is the use of another materials eksapt compass

what is the median,centroid,incentre circumcentre
