2 Inthe given figure polla. Tis the midpoint of theif asla POR) = x ar (PST), then find the value of x​

Answer»

Step-by-step explanation:

The BASIC proportionality THEOREM STATES that if a LINE is drawn parallel to one side of a triangle and it intersects the other two sides at two distinct POINTS then it divides the two sides in the same ratio.

It is given that PE=4 cm, QE=4.5 cm, PF=8 cm and FR=9 cm.

Using the basic proportionality theorem, we have

EQ

PE

=

4.5

4

=0.88

FR

PF

=

9

8

=0.88

Since

EQ

PE

=

FR

PF

Hence, EF is parallel to QR.
