Kiran Loves dogs very much. She wish to make room for the street dogs of triangle shape in which BC = 40.5 m , ∠B= 450 and AB – AC = 20.5 m
(a) Construct the triangle taking measurement of sides in proportion. (b) What ideas promote here

Dear Student,
Please find below the solution to the asked query:
We follow these steps to form our triangle ABC : given angle is = 45 , BC = 40.5 m = 4050 cm = = 8.1 cm and AB - AC = 20.5 m = 2050 cm = = 4.1 cm
Step 1 : Draw a line BC = 8.1 cm
Step 2 :Take any radius ( Less than half of BC ) and center " B " we draw a semicircle that intersect our line BC at "P " . With same radius take center " P " draw an arc that intersect our semicircle at " Q " And with same radius take center " Q " draw an arc that intersect our semicircle at " R " .
Step 3 : With same radius take center " Q " and " R " draw two arcs that intersect each other at " S " . Join line BS , that intersect our semicircle at " T "
Step 4 : With same radius take center " P " and " T " draw two arcs that intersect each other at " U " . Join BU . and extend it to V , we get VBC =45
Step 5 : Take radius of 4.1 cm and center " B " draw an arc that intersect our line BV at " W " . Join CW
Step 6 : Now take radius more than half of CW and cneter " C " and " W " draw two arc from both points on both side of line CW, and these arcs intersect at " X " and " Y " .
Step 7 : Join line XY and that intersect line BV at " A " .
This is our required triangle ABC .

b ) Here we promote idea of making shelters for straw dogs .
