Steps of Construction: • 1. Join the centers O and O'. • 2. Find mid-point M of OO' by drawing perpendicular bisector of OO'. • 3. Find mid-point N of MO' by drawing perpendicular bisector of MO' . • 4.Taking point N as Centre and radius equal to MN =NO' draw a circle . • intersecting the circle with Centre O' at points P and P'. • 5. Draw a line through the points P and M touching the second circle at the point Q . • 6. Draw a line through the points P' and M touching the second circle at the point Q'. • 7. Thus PQ and P'Q' are the required transverse or internal common tangents • to two equal circles . • • 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. • • • Linear Equations and Inequalities Unit#7 Class 9th Mathematics (Sci) • https://www.youtube.com/playlist?list... • • • Practical Geometry_Triangles Unit#17 Class 9th MATHEMATICS (Sci) • https://www.youtube.com/playlist?list... • • • Line Bisectors and Angle Bisectors Unit#12 Class 9th Mathematics (Sci) • https://www.youtube.com/playlist?list... • • • MATHEMATICS (Sci) 10th Class • https://www.youtube.com/playlist?list... • • MATHEMATICS 11th Class • https://www.youtube.com/playlist?list... • • MATHEMATICS 12th Clas • https://www.youtube.com/playlist?list... • • #𝑴𝒂𝒕𝒉𝒆𝒎𝒂𝒕𝒊𝒄𝒔𝑪𝒊𝒏𝒆𝒎𝒂 • #𝑻𝒂𝒖𝒔𝒆𝒆𝒇𝑵𝒂𝒛𝒊𝒓
