I only see "Draw a 105 degree angle" above.

OpenStudy (anonymous):

would you like me to re write the question ? @mathstudent55

OpenStudy (mathstudent55):

No need.

OpenStudy (mathstudent55):

Here's my way of doing it.

OpenStudy (mathstudent55):

Start with a line, and mark two points on the line. |dw:1440958648016:dw|

OpenStudy (anonymous):

okay ive done that

OpenStudy (mathstudent55):

We are going to draw a square segment AB as a side. |dw:1440958758007:dw|

OpenStudy (mathstudent55):

Open the compass to AB and center it at A and draw an arc. Using the same opening, center it at B and draw an arc. |dw:1440958818783:dw|

OpenStudy (mathstudent55):

Now we want to draw a perpendicular to line AB through point A and a perpendicular to line AB through point B. Open the compass to any opening between AB. Center the compass at A and draw and two arcs on line AB, one on each side of A. |dw:1440959091893:dw|
