Find the verticesof the triangle formed by joining the midpoints of the sides of the triangle with vertices (3,3),(3,5) ,(2,4) |
|
Answer» ong>ANSWER: Let A(3, 3) , B(3, 5) , C(2, 4). Step-by-step EXPLANATION: Let P, Q and R be vertices of the new ∆. By using midpoint formula (section formula), P(X, y) = (3+3/2 , 3+5/2 ) = (6/2 , 8/2) P(x, y) = (3,4) Q(x, y) = (3+2/2 , 5+4/2) = ( 5/2 , 9/2 ) Q (x, y) = (2.5,4.5) R(x, y) = (2+3/2 , 4+3/2) = (5/2 , 7/2) R(x, y) =(2.5,3.5)
The vertices of the new ∆ are P(3,4) ,Q(2.5 , 4.5) and R(2.5 , 3.5). |
