Question

Triangle ABC and triangle PQR are similar and have the same orientation. The endpoints of the hypotenuse of triangle ABC are B(-5, -7) and C(-3, -3). The hypotenuse of triangle PQR is on the same line as the hypotenuse of triangle ABC and is twice the length of BC.

Answer 1

(-3,-3) is the midpoint

(-5,-7) is left endpoint.

The right endpoint is (x,y)

(x + -5)/2 = -3 ---> x + -5 = -6 ---> x = -1

(y + -7)/2 = -3 ---> y + -7 = -6 ---> y = 1

(-1,1) is the right endpoint
