# Definition of Obtuse Angle - MATH.

The definition of obtuse angles is “The angles between 90 degrees to 180 degrees are called as obtuse angles”. Here Between means we should not consider 90 and 180 degrees. Except these two angles, any angle which is between them is called as obtuse.

They just form a straight line when they do. And since this angle is also greater than 90 degrees, it's obtuse as well. Lesson Summary. An obtuse angle is any angle larger than 90 degrees. In. For each angle you find, write down the name of the streets that intersect and measure the angle with a protractor to confirm it is an obtuse angle. Record each of your findings in the table below.

Obtuse Angled Triangle Definition A triangle whose any one of the angles is an obtuse angle or more than 90 degrees, then it is called obtuse-angled triangle or obtuse triangle. The sum of the interior angles of the obtuse triangle is equal to 180 degrees only. This means the angle sum property for any triangle remains the same. An obtuse angle is an angle that is larger that 90 degrees but smaller than a straight angle (180 degrees). The following table shows the different types of angles: right angles, acute angles, obtuse angles, straight angles, reflex angles and full angles.

An acute angle makes a sharp point, while an obtuse person is not all that sharp intellectually. Appropriately, obtuse has roots in the Latin obtusus, meaning “dull” or “blunt.”.
