What is the Meaning & Definition of Obtuso

The word obtuse is used in our language to refer several issues. One of these many uses is to refer to that which has no end, i.e. to objects, elements that do not have a tip is called them how obtuse. For example, a pencil or a blunt tool will discuss in terms of obtuse.
Obviously that when an element should have tip and no presents it because it spent or by any other situation will see diminished its effect or the utility that you may currently have. We must mention that it is also common that when a tool or utensil is obtuse speak in terms of mocho.
The opposite would be an item sharp and pointed.
On the other hand, the word obtuse is used widely to refer to a person who is unable to understand any thing or situation quickly and easily; or also used much when one person can understand but gets foolish because for example do not agree with something and then does not understand what says despite his stance or idea is not correct but is rather wrong.
The obtuse Word applied to a person can then be used to indicate that it is awkward and lerdo in understanding or that he is a fool.
Worth mentioning is also that this respect has an extremely pejorative use. Meanwhile, the other side would talk about someone smart and clever.
In another field in which the term is widely used is mathematics where it is used to refer to one of the angles that studies the matter, obtuse angle, which is characterized by measuring more than 90 ° but less than 180 °. Remember that the right angle measures 90 °, the plain is flat and the oblique is so called precisely because its form is not straight.
