to tell what the angle is
An angle of 90 degrees is a right angle.
its called a right angle!
When lines met or cross at a right angle are perpendicular lines.
An angle which has measure between 90 degrees and 180 degrees is an obtuse angle.
to tell what the angle is
An angle of 90 degrees is a right angle.
Angle C is an acute angle.
its called a right angle!

by how long it is
no
There is no angle "between" one hand of a clock.
An angle which has measure between 90 degrees and 180 degrees is an obtuse angle.
there is repulsion between lone pair and bond pair for example in water molecule oxygen has lone pair which repells the bond pair due to this bond angle decreases simply ddue to repulsion btween lone pair to lone pair or lone pair to bond pair angle varies
Accute because the angle is less than 90 degrees
One pair of opposite angle is greater than a right angle.
