27- EXERCISE-13.2 Q6.Circumscribe and Inscribe circles with regard to a right angle triangle.

Steps of Construction: 1. Draw a line segment mAB=3cm. 2. With Centre at A, draw an arc of radius 4cm. 3. With Centre at B, draw another arc of radius 5cm which cuts the previous arc at point C. 4. Join C with A and B. 5. Thus ABC is the required right angle triangle. 6. Draw the right bisector of AB. 7. Draw the right bisector of AC which intersects right bisector of AB at point O. 8. With Centre at O and radius mOA=mOB=mOC draw a circle. 9.This is the required circumscribe circle. 10.Draw (AD) ⃗ the angle bisector of ∠A. 11. Draw (BE) ⃗ the angle bisector of ∠B which intersects (AD) ⃗ at point I. 12. From I draw IF perpendicular to AC. 13. IF intersects AC at point G. 14. With Centre at I and radius IG draw a circle. 15. This is the required inscribe circle. 16.Now label the figure. 17. We observe that radius of circumscribe circle is 2.5 cm and radius of inscribe circle is 1 cm. The word Geometry is derived from two Greek words Geo(earth) and Metron (measurement). Geometry means measurement of earth or land. Geometry is an important branch of Mathematics which deals with shape, size and position of Geometric figures. Euclid’s Elements has been referred to as the most successful and influential Textbook ever written on Geometry. A circle of any radius can be constructed by rotating a compass about a fixed point O. Circle is a locus of points whose distances from a fixed point is same #PracticalGeometry #InscribeCircle #CircumScribeCircle Radius is the distance from Centre to boundary of the circle. Diameter is a chord passing through the Centre of circle. Linear Equations and Inequalities Unit#7 Class 9th Mathematics (Sci) https://www.youtube.com/playlist?list...
