Sir is explaining perfectly

Justification
Draw a triangle ABC as though you solved this.
Now along the baseline draw PB = AB and CQ = AC
Notice angle ABC is external to triangle APB.
Angle ABC is then equal to the sum of the two remote angles ie angle APB + angle PAB
PB=AB so this triangle is isosceles. These two angles then are equal to each other.
They are equal to 1/2 angle ABC.
Handle the right hand side similarly.
So lets start over.
You have line PQ equal to the perimeter.
Draw angle APB = 1/2 desired angle B.
(He does this by drawing in the entire angle B and then bisecting that).
Draw angle AQC = 1/2 desired angle C.
(Same reasoning as on the left. Angle C is external to triangle ACQ which is isosceles. AC=CQ, Base angles are equal. So angle ACQ = 1/2 ACB)
The line you drew at P meets the line through Q at point A.
So where...exactly on the baseline DO YOU put point B?
If you draw a perpendicular bisector to line PA, you have these 2 line segments formed from PA as congruent, the 90 degree angles congruent, and the shared perpendicular line congruent. By SAS the two triangles formed are congruent.
Notice this makes line AB=BP so indicates where to put point B.
Angle PAB= Angle BPA as appropriate for an isosceles triangle. The sum of these two angles = the exterior angle ABC.
You have similar reasons on the Right Hand SIde for locating point C.

Hi brother..how can the perimeter of AB+CA+BC can be 11cm...
To construct a triangle given its perimeter and its 2 base angles.
Given the base angles , say angle B and angle C and BC+CA+AB , you have to construct the triangle ABC. In this way the question is in my textbook....pls answer me....

[@Dream-iy1xc]

Sir , why are you changing the radius of compass ? For 3.2 cm you are taking more than 8 cm radius because ur arc won’t intersect in the extended line . Then what is the purpose of this video if your diagram is not accurate . You are explaining well but you are trying to cover up mistakes in your drawing .. this is just my feedback sir . Next time please don’t change the radius of compass .
