All the angles in an octagon are obtuse. (Obtuse means greater than 90 degrees.)
triangle
An obtuse angle because 98 degrees is greater than 90 but less than 180 degrees
Angles fall into 4 categories and they are:- Acute angles are greater than 0 but less than 90 degrees Right angles are 90 degrees Obtuse angles are greater than 90 but less than 180 degrees Reflex angles are greater than 180 degrees
Angles greater than 90 but less than 180 degrees are obtuse angles Angles greater than 180 but less than 360 degrees are reflex angles
Obtuse angles are greater than 90 degrees but less than 180 degrees. Straight angles are exactly 180 degrees. Reflex angles are greater that 180 degrees.
There are four different kinds of angles and they are:- Acute angles are greater than 0 but less than 90 degrees Right angles are 90 degrees Obtuse angles are greater than 90 but less than 180 degrees Reflex angles are greater than 180 degrees
Any closed shape can have angles greater than 90 degrees. A triangle doesn't need to have any, but it can have one of them if it wants to. A shape with four sides doesn't need to have any, but it can have 2 or 3 of them if it wants to. Shapes with more than 4 sides must have some.
Acute angles are greater than 0 but less than 90 degrees Right angles are 90 degrees Obtuse angles are greater than 90 but less than 180 degrees Reflex angles are greater than 180 but less than 360 degrees A full turn is 360 degrees
Acute angles are greater than 0 but less than 90 degrees Obtuse angles are greater than 90 but less than 180 degrees Reflex angles are greater than 180 degrees but less than 360 degrees
Angles are measured in degrees, minutes and seconds Acute angles are greater than 0 but less than 90 degrees Right angles are 90 degrees Obtuse angles are greater than 90 but less than 180 degrees Reflex angles are greater than 180 but less than 360 degrees A full rotation is 360 degrees
They are as follows:- Acute angles are greater than 0 but less than 90 degrees Right angles are 90 degrees Obtuse angles are greater than 90 but less than 180 degrees Reflex angles are greater than 180 but less than 360 degrees A full rotation is 360 degrees
