CONGRUENCE OF SIMPLE POLYGONS B5

Prove that ∆PQR and ∆RST are congruent in the figure below.

Solution

Given: figure PQRST.

Required to prove: ∆PQR and ∆RST are congruent

Proof: PR= RT    (given)

<QPR = <RTS = 40⁰ (given)

<PRQ = <SRT (opposite angles)

Hence ∆PQR and ∆RST by AAS rule (proved)
