Question

In triangle pqr , qr=7.5cm, angles qpr=110° and pqr+pr=8.3cm construct the triangle pqr and draw its circumcircle

Answer 1

Answer :
We follow these steps to form our triangle PQR  :  But here we can form if given angle is ∠PQR = 110°

Step 1 :  Draw a line QR =  7.6  cm

Step 2 :  With the help of protector form 110° at point  " Q "  , As  : ∠ RQX  =  110°

Step 3 :  Take radius of  8.3 cm and center "  Q "  draw an arc that intersect our line QX at " Y " .

Step 4 :  Join RY .

Step 5 : Now take radius more than half of RY and cneter "  R " and " Y "  draw two arc from both points on both side of line RY , and these arcs intersect at " A "  and " B " .

Step 6 :  Join line AB and  that intersect line QY at "  P " .

This is our required triangle PQR .

now to draw its circumcircle draw medians and for that bisect each and every side of the triangle and when median intersects we get a centroid.
measuring the point of centroid to any part of the triangle is radius and draw a cicle therefore it will be the required circumcircle
