Draw a pair of triangle to a circle of 5cm which are inclined to each other at an angle of 60 |
| Answer» Steps of construction:\tDraw a circle with centre O and radius 5 cm.\tDraw any radius OT.\tConstruct.\xa0{tex}\\angle TOT\' = 180^\\circ - 60^\\circ = 120^\\circ {/tex}\tDraw and\xa0{tex}TP \\bot OT{/tex}{tex}T\'P \\bot OT\'{/tex}. Then PT\'\xa0and PTare the two required tangents such that.\xa0{tex}\\angle TPT\' = 60^\\circ {/tex} Here, PT = PT\'. | |
