Question 1020175
.
Why we cannot construct triangle with conditions such as PQ is 4cm and angle pqr is 70 degrees and angle of qrp is 105 degree ?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


Who said you we can not?


In opposite, we can !


Take your segment PQ of 4 cm long.


Release the ray QR making 70 degree with PQ.


Release another ray from the point P into the same half-plane, making the angle 5 degree with PQ.


The intersection point R will be the third vertex of the triangle.


Simple like an orange.
