Free webinar on Robotics (Block Chain) Learn to create a Robotic Device Using Arduino
30th Jan @ 5:00PM for Grade 1 to 10
in a triangle ABC , A=90°,CA =AB and D is a point on AB produced. prove that : DC2- BD2=2AB.AD in a triangle ABC , A=90°,CA =AB and D is a point on AB produced. prove that : DC2- BD2=2AB.AD
DC^2 = (AC^2 + AD^2) = { AB^2 + (AB + BD)^2} = { AB^2 + AB^2 + BD^2 + 2 AB*AD } = { 2AB^2 + 2 AB*AD } + BD^2 = { 2AB (AB + AD) } + BD^2 = { 2 AB * AD } + BD^2 or, DC^2 = 2AB*AD + BD^2 or, DC^2 - BD^2 = 2AB*AD
