I am L.
That would be the letter, "Ell". "L" "E", "F", "H", and "T" also have right angles in them, but "L" is the only letter with just one right angle in it.
Any letter can be used for any angle. It is conventional, though, to go in one direction around any polygon.
It is: "angle a is not a right angle" or "angle a is greater than or less than a right angle".
If you mean the capital letter "F" there is 3.
A right angle measures 90 degrees
No but the capital letter L has a right angle
L
If you mean which alphabet letter, an L has one right angle; a T has a right and left acute angle.
A capital T
It is a right angle of 90 degrees
4
Probably E - since it has four right-angles.
Well, you can write all capital letters and find out.
That would be the letter, "Ell". "L" "E", "F", "H", and "T" also have right angles in them, but "L" is the only letter with just one right angle in it.
A right angle of 90 degrees can be seen in the letter F
The capital letter E has no acute angles but it does have right angles.
Because a right angle is 90 degrees and perpendicular lines meet at right angles as for example as in the capital letter L
