Triangles are classified into acute and obtuse angles. In geometry, an acute angle is less than 90° and an obtuse angle is greater than 90° but less than 180°.
As a result, 78 degrees represents an acute angle.

A angle more than 90 degrees is called?
An Angle between 90 degrees and 180 degrees is OBTUSE. NB An angle less than 90 degrees is ACUTE An angles between 180 degrees and 360 degrees is REFLEX.
What do all the angles in a obtuse triangle if the obtuse angle is 120 Degrees?
If triangle has one obtuse angle other two angles are acute. Since, sum of angles of triangle is 180.
If an angle measures 245 what is the name of the angle?
obtuse angle
If an angle measure 270 degrees what kind of angle is it?
That's a reflex angle. 0 to <90 Acute angle 90 Right angle >90 to <180 Obtuse angle 180 Straight angle >180 to <360 Reflex angle 360 called Full circle
What are the trigonometric function of an acute angle?
The trigonometric functions are sine, cosine and tangent along with their reciprocals and the inverses. Whether the angle is acute or obtuse (or reflex) makes no difference).
