Triangle PQR has vertices P(-3, -1), Q(-1, 7), and R(3, 3), and point A and B are midpoints of PQ and RQ, respectively. Use coor

andrezito [222]

Answer:

Part a) The figure a shows that AB is parallel to PR. Please see attached figure a.

Part b) The length of AB is half the length of PR

Step-by-step explanation:

Part A)

Let M be the midpoint formula between points A(x₁, y₁) and B(x₂, y₂)

$M=({\displaystyle {\frac {x_{1}+x_{2}}{2}}, {\frac {y_{1}+y_{2}}{2})$

Let A be the midpoint of P(-3, -1) and Q(-1, 7)

The coordinates of the midpoint of P(-3, -1) and Q(-1, 7):

$Mpq{} =({\displaystyle {\frac {-3+(-1)}{2}}, {\frac {-1+7}{2})$

$Mpq{} =(-2, 3)$

Let B be the midpoint of Q(-1, 7) and R(3, 3):

$Mqr{} =({\displaystyle {\frac {-1+(3)}{2}}, {\frac {7+3}{2})$

$Mqr{} =(1, 5)$

The figure a shows that AB is parallel to PR. Please see attached figure a.

Part B)

The point A has the coordinates: A(-2, 3)

The point B has the coordinates: B(1, 5)

The distance formula is: $d={\sqrt {(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}$

So, the length of AB $={\sqrt {(1-(-2))^{2}+(5-3)^{2}$

= $\sqrt{9+4}$

= $\sqrt{13}$

= $3.6056$

And, the length of PR $={\sqrt {(3-(-3))^{2}+(3-(-1)^{2}$

= $\sqrt{36+16}$

= $\sqrt{52}$

= $2\sqrt{13}$

= = $7.2111$

As the length of AB = 3.6056 and the length of PR = 7.2111

So, it is clear that the length of AB is half the length of PR.
