Math's 2 lesson 3 triangle practice set 3.5 | full practice set 3.5

                     practice set 3.5

                            (Q1)
= ∆XYZ~ ∆LMN
/_X=/_L        .....(corresponding angles
/_Y=/_M        of similar triangle)
/_Z=/_N

XY/LM=YZ/MN=XZ/LN
        ....(corresponding sides of similar triangle)


                           (Q2)
= XY =4 CM , YZ=6 CM, XZ=5 CM,
PQ =8 CM
∆XYZ ~ ∆PQR

XY/PQ = YZ/QR = XZ/PR
        ......(corresponding sides of similar triangle)

* 4/8= 6/QR =5/PR                 .....(1)

*4/8 = 6/QR            ....[FROM (1)]
QR*4=8*6
*QR= 8*6/4 = 2*6/1

*QR =12CM

4/8=5/PR
                                ......[FROM (1)]
* 4*PR=8*5

* PR = 8*5/4 = 2*5/1

* PR = 10 CM

PR = 12 CM , PR = 10 CM
