How is AB is perpendicular to CD How many 90 and deg angles are formed by the intersection?
If AB is a perpendicular bisector of CD then four 90 degreee angles are formed.
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.
How many pairs of perpendicular sides are there in a square?
Perpendicular would be at a right angle. If your sides are abcd, then ab, bc, cd, and da are perpendicular pairs.
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.
If AB is parallel to CD and the slope of CD is -8 what is the slope of AB?
If the lines AB and CD are parallel then they both will have the same slope of -8 but with different y intercepts
