In each case find an equation for the line passing through the origin which is also perpendicular to the line joining the two points given.
a (4,3), (-2, -9)
b (0, 3), (-10, 8)​

To show that polygon abcde is congruent to polygon fghij, a must be used to make the two polygons coincide. a sequence of two transformations that can be used to show that polygon abcde is congruent to polygon fghij is .

Pls! does anybody know a shortcut for answering these types of questions in the future?

Which approach to the theory-and-research cycle does the following sequence reflect: (1) specific observations suggest generalizations, (2) generalizations produce a tentative theory, (3) the theory is tested through the formation of hypotheses, and (4) hypotheses may provide suggestions for additional observations?
