Answer to Question 2:

 

1. Open the compasses to a distance greater than half the distance between F and G.

2. Put the compass point on F and draw a semicircle that crosses line FG.

3. Repeat 2. with the compass point on G.

4. The two semicircles will intersect at two points, so use the straight edge to draw a line between them.  This line will be perpendicular to line FG.

Answer to Question 3:
The triangles are similar if the corresponding angles are EQUAL;
So, angle B = angle Q, angle A=angle P, angle C=angle R.
And the corresponding sides of the two triangle must be PROPORTIONATE, namely:
32/24 =28/[3x + 6]   cross multiply
24 x 28 = 32 x [3x + 6]
672 = 96x + 192
96x =672 - 192
96x = 480  divide both sides by 96
x = 480 / 96
x = 5  sub 5 for x in 3x + 6
(3 x 5) + 6 = 21 Length of the corresponding side with x.
