1.In sigh convention always object /image distance should b measured from pole irrespective of concave /convex.
2.when object/image distance is from right(⇒) then distance is +ve
3.when image/object distance is from left opp. 2 the upper case then -ve
4.when image is below principle axis then -ve
5.if object is above principle axis it is +ve
2.when object/image distance is from right(⇒) then distance is +ve

4.when image is below principle axis then -ve
5.if object is above principle axis it is +ve

Sign Convention for Reflaction by Spherical Mirrors use the pole of the mirror as Origin. The principal axis of the mirror is taken as the x-axis of the coordinate system.
✔️ The object is always placed to the left of the mirror.
✔️ All distance parallel to the principal axis are measured from the pole of the mirror.
✔️ All the distance measured to the right of the orgin are taken as positive while those measured to the left of the origin is taken as negative.
✔️ Distances measured perpendicular to and above the principal axis are taken as positive.
✔️ Distance measured perpendicular to and below the principal axis are taken as negative.
