Question

PQRS is a quadrilateral with SQ as one of its diagonals.if SR=PQ=4cm, SR=
SQ=5 cm and SQ is perpendicular to both SR and PQ, then show that ar(triangle PSQ)= ar(triangle SRQ).

Answer 1

bro u prove it congruent by hypotenuse side test ( HST)
since SQ is perpendicular to SR n PQ and SR=PQ, therefore the quadrilateral is a rectangle.
so to prove the triangles congruent,
diagonal of 5 cm as a common side ,
since the the lines r perpendicular the angles r 90,
and the opposite sides r congruent.
this u can prove the triangles congruent.
