CIRCLES- NCERT MATHS EXEMPLAR SOLUTIONS- EX- 9.4-Q1 to Q3. Q1. If a hexagon ABCDEF circumscribe a circle, prove that AB + CD + EF = BC + DE + FA. Q2. Let s denote the semi-perimeter of a triangle ABC in which BC = a, CA = b, AB = c. If a circle touches the sides BC, CA, AB at D, E, F, respectively, prove that BD = s – b. Q3. From an external point P, two tangents, PA and PB are drawn to a circle with centre O. At one point E on the circle tangent is drawn which intersects PA and PB at C and D, respectively. If PA = 10 cm, find the the perimeter of the triangle PCD. 1.class 10 2. Ncert maths exemplar solutions 3. Circles exemplar solutions chapter 9 4. Exemplar solutions circles class10 5.
