Complimentary angles.
180 degrees i believe
Here's some angles for reference: 0 degrees-89 degrees are acute. 90 degrees is a right angle. 91 degrees-179 degrees are obtuse. 180 degrees is a straight angle.
An angle measuring 180 degrees is commonly referred to as a straight angle.
acute angle(< 90 degrees), right angle, obtuse angle ( > 90 degrees) and reflex angle ( > 180 degrees)
Despite their fancy names, all triangles internal angles add up to 180 degrees.
Ángulo agudo: between 0 and 90 degrees. Ángulo obtuso: between 90 and 180 degrees. Ángulo recto: 90 degrees.
Acute angles do not have specific names.
It depends on the state you're in. In California, it's how to measure angles and degrees, names of shapes and some stuff about triangles.
If the angle is over 90 degrees the angle is obtuse, smaller than 90 degrees the angle is acute and over 180 degress the angle is a reflex angle
That depends upon the lengths of the sides. If the three side lengths are A, B and C, then the three angles are given by:- # a = cos-1( (B2 + C2 - A2) / (2BC) ) # b = cos-1( (A2 + C2 - B2) / (2AC) ) # c = cos-1( (A2 + B2 - C2) / (2AB) )
There are no angles: the only intersections are of curves.
All triangles have 3 sides and 3 interior angles that add up to 180 degrees and they are: scalene, right angle, obtuse, isosceles and equilateral triangles
