Question

in triangle PQR, point s and T are the midpoint of the side PQ and PR respectively if P is equal to 6.2 then find the length of QR

Answer 1

ANSWER

the length of QR=  12.4

Step-by-step explanation:

Given :  

In ∆PQR, points S and T  are the midpoints of sides PQ  and PR respectively.  

Length of ST = 6.2  

To Find : Length of QR.

Solution :

Refer the attached figure

Since S and T  are the midpoints of sides PQ  and PR respectively and ST is parallel QR

So, by mid segment theorem i.e. the segment joining the midpoints of any two sides will be parallel to the third side and half its length in a triangle

Thus the length of QR = 12.4
