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.**
