A 45-degree angle is called an acute angle. In geometry, an acute angle is an angle that measures between 0 and 90 degrees. It is less than a right angle (90 degrees) and is commonly found in various geometric shapes and calculations.
Oh, dude, that's an acute angle! It's like when you're trying to fit into skinny jeans but they're just too tight - that's how acute angles are, they're less than 90 degrees but still trying to squeeze in there. So yeah, less than 45 degrees? Acute angle all the way.
Yes. Any angle smaller than 90 degrees are considered an acute angle.
These are all acute angles. Any angle less than 90 degrees is an acute angle, and any angle greater than 90 degrees is an obtuse angle. 90 degree angles are called right angles. 180 degrees is considered a straight line, and 360 degrees is considered a circle.
The exterior angle of a general octagon is any angle less than 180 degrees. The sum of the exterior angles of a polygon is 360 degrees. If the octagon is regular, then each of its 8 exterior angles is equal to 360/8 = 45 degrees.
