Question

This is the second part pls answer. in case you can't see anything notify me​

Answer 1

K = 2cm

Explanation:

The figure are similar by AA similarity theorem

A-A similarity theorem was deals with at least the two angles are congrunt then we said that figure is similar.

So in the given figure ∆SRT ~ ∆QPT and if the two triangles are dimilar their coresponding side ratio are equal and their angles are congrunt .

Now our question is to find the scale factor . let it be K

K = QP/SR = PT/RT = QT/ST

K = 4cm/2cm = 6cm/3cm= 6cm /3cm

K = 2cm = 2cm = 2cm ... so the scale factor is 2cm.
