Answer:
here is your answer mate
Step-by-step explanation:
Converse of Pythagoras theorem
if the square of the length is the longest side a triangle is equal to the sum of the squares of other two sides then the triangle is a right triangle
that is in triangle ABC if c²= a²+b² the angle C is a right traingle, Traingle PQR Being the right angle
we can prove this contradiction
Let us assume that c² = a² + b² in Traingle ABC and the Traingle is
not right traingle
Now consider another triangle triangle PQR we construct so that PR = a , QR = b and angle is right angle
By Pythagoras theorem (PQ)² = a²+b² But we know that a² + b² = c² and c = AB
So (PQ)² : a²+b²: (AB)²
That is (PQ)² = (AB)²
since PQ and AB are length of sides we can take positive square root
PQ = AB
that is all the three sides of the triangle PQR are congruent to the three sides of triangle ABC so the two triangles are congruent by the Side × Side × Side congruence property
since triangle ABC is congruent to triangle PQR and PQR is right traingle , Traingle ABC must be Right Traingle There is a contradiction therefore our assumption must be wrong
