Question

Rectangle PQRS is shown with its diagonals, PR and QS. What type of triangle is △STR? help please

Answer 1

PQRS is a rectangle so its diagonals of a rectangle have the same length and intersect in their middle → PT=TR=TQ=TS

triangle SRT: sides TR and TS are equal

a triangle with 2 equal sides is isosceles

Isocel T-SRT
