Q.11. In the figure, AY perpendicular to ZY and BY perpendicular to XY such that AY = ZY and BY = XY. Prove that AB = ZX. Share with your friends Share 3 Neha Sethi answered this Solution : Clearly ∠ZYA=∠XYB=90° given ⇒∠ZYA+∠AYX=∠XYB+∠AYX⇒∠ZYX=∠AYB ...1Consider △AYB and △ZYXAY=ZY givenBY=XY given∠AYB=∠ZYX using 1So, △AYB≅△ZYX SAS⇒AB=ZX c.p.c.t 7 View Full Answer Kiran Sharma answered this in triangle ayb & zyx ay = zy(given) by=yx(given) angle zya+angle ayx = angle byx +angleayx (adding angle ayx to both the sides and zya &byx are 90 each) so, triangle ayb = congruent = triangle zyx by cpct ab=zx 3
