Help me in my question plz​

Answer 1

Step-by-step explanation:

You have to measure it by usinge scale. Its not possible to measure line on phone.

Measure the lines and then put values it will automatically satisfy the given relations.

Answer 2

Given parameters :

A line segment PR is given that has Q point as it's midpoint . We need to calculate and verify that ,

• a ) PQ + QR = PR
• b ) PR - PQ = QR

Concept insight :

Midpoint of a line segment divides it into two equal parts .

Assumption :

Let the length of PR be 8 cm .

Now as Q is the midpoint of the line segment PR .

PQ and QR would be 4 cm .

Desired solution :

Substitute the values respectively in the given equations .

• a ) PQ + QR = PR
• 4 + 4 = 8 cm
• 8 cm = 8 cm
• LHS = RHS
• Hence verified

Take the second case

• b ) PR - PQ = QR
• 8 - 4 = 4
• 4 cm = 4 cm
• LHS = RHS
• Hence verified
