a triangle anything with 3 sides is a triangle
It could possibly be a triangle depending on its base
In its normal orientation the parallel sides of a trapezium are horizontal. In that case it will have no perpendicular lines. But turn the figure through 90 degrees and it has two!In its normal orientation the parallel sides of a trapezium are horizontal. In that case it will have no perpendicular lines.

a triangle anything with 3 sides is a triangle
A triangle will always be composed of a minimum of one horizontal and one verticle line with a third line connecting them together. Therefore, it would be impossible to compose a "legal triangle" with three horizontal lines.
When the line of an image on the two parallel horizontal sides are even, i.e. straight.
It could possibly be a triangle depending on its base
a rectangle in the middle, 4 squares surrounding it then attached to one of the horizontal sides, another rectangle which is also horizontal.
First you would want to graph the rectangle. For example, The corners of the rectangle are (0,0), (0,2), (3,0) and (3,2). You would have a rectangle with the vertical sides being 2 units in length and the horizontal sides being 3 units. The "easy" way to find the area of a rectangle is to multiple the length of the vertical sides by the horizontal sides. In this example, 2*3=6. The calculus way would be to setup an integral from a to b of f(x)dx. a and b are the end points for x values. i.e. a <= x <= b. In this example, a = 0 and b = 3. f(x) is the function y=2. The integral from 0 to 3 of 2dx = 6.
it can be folded horizontally and the sides match each other
