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.
NO!!!! The names of different types of angles are. 0 degrees ; NO angle Greater than '0' , but less than 90 degrees ' ACUTE Angle 90 degrees ; Right angle Greater than 90 degrees , but less than 180 degrees ; OBTUSE. 180 degrees ; a Straight Line Greater than 180 degrees but less than 360 (0) degrees ; REFLEX .
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.
An OBTUSE Triangle. Names for other types of triangle. Equilateral [ all angles 60 degrees and all sides the me length). Isosceles ; Two angles are equa; and two sides the same length Obtuse ; one angle between 9 degrees and 180 degrees. Right-Angles ; One right angle. Scalene ; three angles unequal and three sides unequal length.
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
The two names of set squares are the right-angle triangle and the bevel. The right-angle triangle is commonly used in drafting and construction for creating and measuring right angles, while the bevel is used to measure angles other than 90 degrees.
