3. Obtuse angle

                  When an angle measures more than 90 degrees, it is called an ‘Obtuse’ angle.

                  In  the  image,  lines  AB and  BC  form  an  angle  ABC at  the  point  of  contact  B, which  measures
                  120 degrees.
                  Hence, angle ABC is an obtuse angle.




                                                                         °







                  4. Straight angle

                  When an angle measures exactly 180 degrees, it is called a ‘Straight’ angle. A straight angle is a

                  straight line where the second line lies flat on the other side of the first line.
                  In  the  image,  lines  AB and  BC  form  an  angle  ABC  at  the  point  of  contact  B  which  measures
                  180 degrees.

                  Hence, angle ABC is a straight angle.








                  5. Reflex angle

                  When an angle measures greater than 180 degrees, but smaller than 360 degrees, it is called an
                  ‘Reflex’ angle. In the image, lines AB and BC form an angle ABC at the point of contact B which
                  measures 220 degrees.

                  Hence, angle ABC is a reflex angle.














                  Program to Find the Type of Angle

                  To create an AI Connect program to determine the type of the angle, create a project. In this project

                  create a Basic Coding activity. Then follow the given steps:
                   Step 1   Create a variable called ‘angle’. Drag out its ‘set’ block. Attach an ‘int’ block to it. Attach
                            an input block that asks the user for a number.
