Obtuse triangle: a triangle with one angle greater than 90 degrees.
An acute angle.
An angle in a four sided shape can have any measure in the interval (0, 360) degrees except 180 degrees.
Hendecagon
36 degrees.
Trigonal Bipyramidal. 90 and 120 degrees
well, if your asking if and acute shape is a wide leaned back angle, well then the answer is no. that's and obtuse angle. and acute angle is smaller than 90 degrees and an obtuse angle is larger than 90 degrees.
An obtuse triangle
An acute angle is an angle of a shape under 90 degrees, an angle over 90 degrees is called an obtuse angle. hope this helps!:D
12 degrees is an acute angle
A right angle triangle. (if it is a triangle)
A right angle triangle.
The measure of an exterior angle depends on the shape.
The angle measures 90 degrees.
It is a right angle
An acute angle.
A reflex angle
Roughly a "v" shape with an angle of 104.5 degrees.
