24-EXERCISE-13.2 Q3.Escribed a circle opposite to vertex A to a triangle ABC.Also measure its radius

Steps of Construction: 1. Draw a line segment mAB=6cm. 2. With Centre at A, draw an arc of radius 3cm. 3. With Centre at B, draw another arc of radius 4cm which cuts the previous arc at point C. 4. Join C with A and B. 5. Thus ABC is the required triangle. 6. Produce the sides AB and AC of triangle ABC. 7. Draw BD the bisector of external angle ∠ B. 8. Draw CE the bisector of external angle ∠ C which cuts the bisector of external angle ∠ B at point I. 9. From I_1 draw IF perpendicular to AB which cuts AB produced at point G. 10. With Centre at I and radius (I G , draw a circle. 11. This is the required escribed circle opposite to vertex A of triangle ABC. 12. E-radius of escribed circle is I G=2.1 cm (Approximately) 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 #EscribedCircle 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...
