What Are Some Real World Examples of an Obtuse Angle?

Most house roofs have angles that aren’t right because the two sides of the roof slope down from it. Other real-world examples of an obtuse angle are the angle between the screen and the base of an open laptop, a hockey stick, an accordion hand fan, and the angle between the wings of a boomerang. Obtuse angles are usually seen when two sides, arms, or surfaces are far apart.

An angle is the amount that two straight lines that meet at a single point turn away from each other. There are five kinds of angles in geometry. An obtuse angle is one that is greater than 90 degrees but less than 180 degrees. A right angle is exactly 90 degrees. A sharp angle is one that is less than 90 degrees. A straight angle is exactly 180 degrees, and a reflex angle is more than 180 degrees. A full angle of 360 degrees could be thought of as the sixth type of angle. In these terms, an obtuse angle is a kind of angle that is bigger than a right angle but smaller than a straight angle.

For people who find it hard to remember or understand the different definitions of angles, the following is a common way to remember them: Acute angles are “cute,” which means they are small; obtuse angles are “obtuse,” which means they are fat or wide; right angles are “right,” which means they are correct or perfect; straight angles are “straight,” like a line; and reflex angles are thought to have good “reflexes,” which means they are bendy or overstretched.
