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
The angle measures 90 degrees.
The measure of an exterior angle depends on the shape.
A right angle triangle. (if it is a triangle)
A right angle triangle.
A reflex angle
It is a right angle
An acute angle.
You can find out the degrees of the angles of shape shape by following these instructions. First you line up the bottom line of the protractor onto a side of a shape. The corner of the shape should be on the tiny dotlike thing in the middle of the bottom line of the protractor. Next, you find out if the angle is obtuse (larger than a right angle), acute (smaller than a right angle), or right. If it's obtuse, you know that it's larger than 90 degrees. You should look at the larger number the other line is pointing at. If it's acute, find you the angle by finding out which number the other line is pointing at. If you think it's a right angle, see if the line's pointing at another number. Otherwise, it's a right angle.
