All angles are made up when two lines or sides vertexes or intersection points, I think.
An obtuse triangle is a triangle with one angle greater than 90 degrees. Since a perpendicular side is a side that forms a right angle with another side, an obtuse triangle can have 0 perpendicular sides if all its angles are obtuse. However, it can also have 1 perpendicular side if one of its angles is a right angle.
no
a right angle, a obtuse angle, and an acute angle.
An obtuse angle is any angle larger than 90°. An obtuse angle is not assigned any specific value.
A traditional kite shape (a point at the top, then widest about 1/3 of the way down, then tapering to another point at the bottom) has one, two or three obtuse (>90 degree) angles. The two angles at the widest point, about 1/3 of the way from the top, are generally obtuse, but don't have to be. The bottom angle is almost never obtuse. The top angle is sometimes obtuse. So if the top angle is obtuse but the side angles are not, a kite shape has one obtuse angle. If the top angle is not, but the side angles are, it has two obtuse angles. If the top and side angles are obtuse it has three.
An obtuse angle.
An obtuse angle
An obtuse angle is only one angle, however if you meant 'how many degrees?' then an obtuse angle contains more than 90 and less than 180 degrees..
Greater than 90 but less than 180 degrees
An obtuse angle is greater than 90° but less than 180°. Any angle within that range is considered to be obtuse.
An obtuse angle is an angle measuring between 90 and 180 degrees
It ha one right angle, two obtuse angles and one acute angle
