Yes, perpendicular lines do form four right angles be cause if you draw one perpendicular line and you look at it you will see that there is one rightside up L then one upside down L one backwards L and one upside down backwards L so that makes four right angles. Hope I helped!! -Taylor
A line which forms a right angle with another line (think an upside-down T) Actually it doesn't have to be upside-down...
if you look at it upside down then 53788078 will be BL0BBLES.
It looks like an upside-down "T".
Because if you turn a nine upside down then it does not look like anything but if you turn a six upside down then it looks like a nine.
Does what look like what under a micrscope. Everything under a microscope is upside down and backwards. So it would look like a backwards if.
Backwards & upside down
Because microscopes and telescopes are made up of mirrors.
It would look upside down.
intrestingly cool
1961 now write it and turn your paper backwards and you'll see the same number. =)

an upside down parabola
Yes, when you look at something upside down, the image will be projected upside down onto your retina, located at the back of your eyeball. However, your brain is able to interpret the image and flip it right side up so that you perceive the object correctly.
its a circle so the figure is round that is why we see each other upside down
Upside down frowns.
Just look at it!
