Answer:
(a + b, c )
Step-by-step explanation:
Using the midpoint formula
given 2 points (x₁, y₁ ) and (x₂, y₂ ) then midpoint is
[ [tex]\frac{x_{1}+x_{2} }{2}[/tex], [tex]\frac{y_{1}+y_{2} }{2}[/tex] ]
let (x₁, y₁ ) = P(0, 0) and (x₂, y₂ ) = R(2a+2b, 2c), then
midpoint = [ [tex]\frac{0+2a+2b}{2}[/tex], [tex]\frac{2c}{2}[/tex] ]
= [tex]\frac{2(a+b)}{2}[/tex], c ] = (a + b, c )
