Why was the term political machine used to describe corrupt political systems in the late 1800s? a) political machines ran very smoothly, like clocks.b) political machines created cycles that turned, like gears.c) political machines were led by factory owners.d) political machines worked like assembly lines.

The correct answer to this question is letter "c) political machines were led by factory owners." The reason why the term political machine used to describe corrupt political systems in the late 1800s is because political machines were led by factory owners.

As we know two triangles are similar by the following Postulates:

1. Side-Side-Side Proportionality

2.Side-Angle-Side Proportionality

3.Angle - Angle Similarity

Given: Triangle MNO is dilated to create triangle PQR on a coordinate grid.

∠N ≅ ∠Q

As to prove similarity of two triangles , line segments that is corresponding sides of triangles can't be congruent.They must be proportional.

As well as we have to select angles in such a way As :ΔMNO~ΔPQR

⇒∠N→∠Q, ∠M→∠P, ∠O→∠R

The option : Angle M is congruent to angle P is true.
