Reflect triangle PQR about y equal to 0
means how to Slove this
plz tell me
Answers
Answer:
In △PQR,
P=(2,1)
Q=(−2,3)
R=(4,5)
Mid-point of PQ=(2x1+x2,2y1+y2)=(22−2,21+3)=(0,2)
Equation of the median through the vertex R is the equation of the line passing through the points (0,2),(4,5)
Since, two points form of the line is y−y1=(x2−x1y2−y1)(x−x1)
∴ Equation of the median is
y−2=(4−05−2)(x−0)
⟹4(y−2)=3x
⟹4y−8=3x
3x−4y+8=0 (Ans)
