ONE!!!
The outside angle of the 'top left of the letter 'F' . It ids obtuse at 270 degrees.
All the rest are orthogonal at 90 degrees.

There are 3 right angles in the letter F
3 right angles.
Three of them
If you mean the capital letter "F" there is 3.
3 right angles.
so a obtuse angle is a triangle or what ever figure made out of rays and line segments and etc. and its is a 180 degree figure so if your talking about a A,B,C,D,E,F figure then the two obtuse angles will be
3 angle
F for corresponding angles and Z for alternate angles
right (90˚) and 180˚ angles
A right angle of 90 degrees can be seen in the letter F
R-0 E-0 A-2 L-0 F-0 U-0 N-0 1-0 there are 2
They are all called f angles or corresponding angles!
