obtuse angle
An angle that measures more than 90 degrees but less than 180 degrees
An obtuse angle is an angle that measures greater than 90 degrees and less than 180 degrees. It is formed by two rays or line segments that originate from the same point and extend in different directions. The angle between these two rays is greater than a right angle (90 degrees) but less than a straight angle (180 degrees).
In geometrical terms, an obtuse angle can be visualized as an angle where one of the rays is pointing towards the inside of the quadrant formed by the other ray. This angle can be found in many geometric shapes such as rhombus, parallelogram, trapezoid, and kite.
An example of an obtuse angle is the angle formed when we hold our arms apart and create a V shape. The angle formed at the point where our arms meet is an obtuse angle. Another example of an obtuse angle is the angle formed by a staircase when the stairs are not perpendicular to the floor.
To measure an obtuse angle, we need a protractor. Place the protractor with its base at the vertex of the angle. Then, align one of the protractor sides with one of the angle sides. Read the angle measurement at the point where the other angle side crosses the protractor scale.
