Step 1: Examine the given figure and make a note of the given angles


Step 2: Based on the given data classify the triangles.

             NOTE: If they given lengths, then find the types of triangles based on lengths.

                         If they given angles,  then find the types of triangles based on lengths.


Step 3: Conclude that the given triangle is a right angle triangle. if you find 90 degrees in the given angles. (Otherwise go for the next step.)

            EXAMPLE:  Angles 45 \degree, 45 \degree, and 90 \degree   \degree

                                  Here we have 90 \degree. so it an right angle triangle.


Step 4: Conclude that it is an acute angled triangle. If all the angle are less that the 90 \degree. (Otherwise go for the next step.)

              EXAMPLE:  Angles 72 \degree, 73 \degree and 35 \degree

                                  Here, All angles are less than 90 \degree


Step 5: Conclude that the given triangle is Obtuse angle triangle. If you find any one of the angle is greater than 90 \degree.

                EXAMPLE: Angles 136 \degree, 20 \degree and 24 \degree

                                    Here One angle is greater than 90 \degree.
