Any angular size between 0 and 90 degrees.
An OBTUSE angle is one whose size is between 90 & 180 degrees.
A REFLEX angle is one whose angle is between 180 & 360 degrees.
NB To correct your English grammar . The question should read ' What size is an acute angle'.
When the noun following the indefinite article 'a', begins with a vowel 'a,e,i,o,u'. then the indefinite article is 'an'. In this case it is 'an acute', NOT 'a acute'.
The question appears to relate to the angles of a triangle. 1) If angle 3 is acute then the other two angles can also be acute. In the case of an equilateral triangle all three angles are equal and acute. 2) If angle 3 is acute and one other angle is obtuse then the remaining angle is acute. 3) If angle 3 is acute and one other angle is a right angle then the remaining angle is acute.
No, but 75 degrees is an acute angle.
obtuse
Yes . Triangle have right acute and obtuse angle except compelete angle.
An acute angle
An acute angle is larger than than 0 degrees but less than 90 degrees (a right angle).
An acute angle by definition, is an angle that measures anywhere from 1º (or less) to 89º as long as it is smaller than a right angle (90º).
It can be an acute, right angle or an obtuse angle depending on its size.
1 acute angle = 1 acute angle
That is an acute angle. An obtuse angle is not acute.
An acute angle
acute angle
An acute angle is an angle less than 90°. So an angle of 17° is an acute angle.
An acute angle has one angle.
This is an acute angle.
Acute angle = <90 degrees Right angle = 90 degrees Obtuse angle = >90 degrees To answer your question, obtuse angle is larger.
An angle less than 90 degrees is an acute angle.
