An obtuse angle is between 90o and 180o.
90o is a right angle.
Between 90o and 180o is an obtuse angle.
180o is a straight angle.
A right angle is like this (look at ray A):
A
^



L> exactly 90o
A straight angle is this (look again at ray A):
A<> 180o is flat
For an obtuse angle, the A should be somewhere between the places where A was in the right and the straight angles.
it is a obtuse angle
no right angle with only one angle is obtuse
obtuse. look in a math book
it looks wierd
Obtuse

They make a pair of acute angles and a pair of obtuse angles. In rotational order, the angles are acute, obtuse, acute, obtuse.
an obtuse angle is greater than 90 degrees and less than 180 degrees
an obtuse triangle is any triangle with an angle over 90 degrees, typically they look like \_ with a line connecting the two rays.
They make a pair of acute angles and a pair of obtuse angles. In rotational order, the angles are acute, obtuse, acute, obtuse.
None. Obtuse means >90°; acute means <90°; a right angle = 90°. See Relevant Answers. Or look up "rectangle" in a dictionary; also "obtuse".
it can be a triangle that is right, acute, or obtuse
