40-To draw transverse or internal common tangents to two unequal circles | Class 10 | geometry

Steps of Construction: 1. Join the centers O and O'. 2. Find mid-point M of OO' by drawing perpendicular bisector of OO'. 3.Taking point M as Centre and radius equal to mMO=MO'draw a circle. 4. Draw another circle with O as Centre and radius equal to r+r', cutting the circle with Centre M at points P and Q. 5. Join O with P and Q. OP and OQ meet the first circle with radius r at Points A and B . 6. Draw O' Q'∥(OPand O' P'∥OQ. 7. Join A with B' and A' with B so that AB' and A'Bare the required common tangents. 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 #InternalTangent #TransverseTangent Radius is the distance from Centre to boundary of the circle. Diameter is a chord passing through the Centre of circle. https://www.noteshint.com Linear Equations and Inequalities Unit#7 Class 9th Mathematics (Sci) https://www.youtube.com/playlist?list...
