3. Sl no: Number of angles
together
Degree Equal parts
1 1 1 degree 360/1=360
2 2 2 degree 360/2=180
3 3 3 degree 360/3=120
4 4 4 degree 360/4=90
5 5 5 degree 360/5=72
6 6 6 degree 360/6=60
7 8 8degree 360/8= 45

4. That is 360/30= 12

5. When we divide a circle into 4 equal parts, how much is each angle,
in degrees
The angle at this corner of the set square is 90 degree

6. When we divide a circle into 8 equal parts,
using other corner of set square, how much
Is each angle at the center?

7. Now find the angles at the corners
of the other set square.
