How do you draw a line segment of root 12cm?
It is easiest to draw it using two right angled triangles.Draw a line AB that is 2 units long. From B, draw BC which is perpendicular to AB and 2 units long. Join AC. From C, draw CD which is perpendicular to AC (clockwise if BC is clockwise from AB, or anticlockwise if BC is anticlockwise) and make CD 2 uinits long. Then AD is a line segment which is sqrt(12) units long.
Joaquin is constructing the perpendicular bisector of line AB. What should be his first step?
Place the point if the compass on point B and draw an arc across AB.
What is the first step in the construction of a line perpendicular to AB and passing through an external point M?
Draw a straight line and with compass mark off two joined arcs above and below the line and then join the arcs together which will produce a perpendicular line.
What does it mean for something to be perpendicular?
For two items (Planes, lines, line segments, ect.) to be perpendicular that means that they meet at a 90 degree angle. Perpendicularity is denoted by the ⊥ symbol. For example line AB ⊥ line CD would mean that the line AB would be perpendicular to the line CD.
If line AB contains the points 4 19 and -3 5 what is the slope of a line perpendicular to AB?
-1/2 or -0.50
