One, and two, respectively.
Shapes are not parallel or perpendicular. Lines are.Every side of a rectangle is parallel to the side opposite it,and perpendicular to both of the sides next to it.
PARALLEL AND PERPENDICULAR LINESParallel lines can run side by side on forever but perpendicular lines make a 90 degree angle.
No triangle can have parallel sides but a right angle triangle has perpendicular sides that meet at 90 degrees
A rectangle
A parallelogram.
All sides of an octagon are parallel to one other side. There are 4 sets of parallel sides.

I'm not sure what you mean by "total height". I guess you mean the perpendicular distance between two parallel opposite sides. Draw the two diagonals to the opposite vertices from one side; they meet at the centre of the octagon, creating an isosceles triangle with the side of the octagon. The perpendicular height from the centre to the side is height/2 The angle at the centre is 360°/8 = 45° (as there are 8 such triangles). The angle at each end of the octagon side is (180° - 45°)/2 = 62.5° Drop a perpendicular from the centre of the octagon to the side of the octagon in this triangle. This forms a right angle triangle with one side height octagon/2, side octagon/2 and hypotenuse largest diagonal/2 → Tan 62.5° = (height/2) / (side/2) = height/side → side = height/tan 62.5° = 85in/tan 62.5° ≈ 44.25 in

A square and a rectangle have perpendicular and parallel lines. The two side lines extending upwards from the base line are perpendicular to the base line. The line extending from each of the side lines across the top is perpendicular to the side lines. The top line is also parallel to the base line, and the side lines are also parallel to each other.

Perpendicular is when a line is at a right angle to another. Parallel lines are side by side and even if they were to go on to infinity, would never meet. Therefore the answer is perpendicular.
the opposite of parallel lines are Perpendicular. A perpendicular angle or line is where there is a 90 degree on each and every side.

Yes, parallel means that two lines do not cross but lay side-by-side. Perpendicular is the opposite of parallel and means two lines intersecting.
