What are facts about acute angles?
Acute angles of angles that have a magnitude less than 90 degrees.
What is an all acute angles?
acute angles are angles that are smaller than 90 degrees. all acute angles are all angles that are less than 90degrees
If an acute angle is supplementary it is always sometimes or never acute?
Supplementary angles total 180o. If one of the angles is acute it is less than 90o so its supplement must be greater than 90o, so it can never be acute.
Is it possible for a pentagon to have all acute angles?
No. If all 5 angles were acute, then they would add up to less than (5 x 90°) = 450°. But the sum of the interior angles of a pentagon is always 540° .
How many acute angles does a trapezoid have?
A trapezoid always has two acute angles. the base angles have to be acute because the lower base angles and the upper base angles are complementary so since the upper base angle is always obtuse, the lower base angles have to be acute.
Does an acute triangle have three angles less than 90 degrees?
Yes. An acute triangle has three angles that individually are less than 90 degrees. Remember you can add the internal angles together in a triangle and they will always add up to 180 degrees.
Are to acute angles supplementary?
no because supplementary means when 2 angles equal 180 degrees. but an acute angle is always less than 90 degrees, so two acute angles cannot add up to equal 180 degrees/be supplementary.
Acute not in math?
Acute is in math, more likely in the geometry area. Acute angles are angles that are less then 90 degrees.
Are vertex angles always acute?
NO they are not.
What is acute angles?
Small angles which have less than 45º
What angles are less than ninety degree?
Acute angles.
What shape can contain no acute angles?
A square has no acute angles. Acute angles are defined as having less than 90 degrees. A square has four 90 degree angles.
