If you mean which alphabet letter, an L has one right angle; a T has a right and left acute angle.
The letter "R".
my answer is R
The capital letter E has no acute angles but it does have right angles.
because its angles are acute
an angle with a acute and right angle
Yes. If its a right angle there has to be an acute angle.
If you write it so the middle angle is a right angle, "K" fits the description.
acute angle
Acute
acute angle
An acute angle has less than 90 degrees and a right angle has exactly 90 degrees, therefore an acute angle is smaller than a right angle.
