Construction of 90 Degree Angle
Construction of 90 Degree Angle
Construction of 90 Degree Angle: In order to construct an angle of measure of , we follow the following steps:
Steps of Construction
STEP I Draw a ray OA. STEP II With O as centre and any convenient radius, draw an arc, cutting OA at P. STEP III With P as centre and the same radius, draw an arc cutting the arc drawn in step II at R. |  |
| STEP IV With R as centre and the same radius as in steps II and III, draw an arc, cutting the arc drawn in step III at S. |  |
| STEP V With R as centre and the same radius, draw an arc. |  |
| STEP VI With S as centre and the same radius,draw an arc, cutting the arc drawn in step V at T. |  |
| STEP VII Draw OT and produce it to B. |  |

7thMy experience with Abhyas is very good. I have learnt many things here like vedic maths and reasoning also. Teachers here first take our doubts and then there are assignments to verify our weak points.
Shivam Rana
7thOne of the best institutes to develope a child interest in studies.Provides SST and English knowledge also unlike other institutes. Teachers are co operative and friendly online tests andPPT develope practical knowledge also.
