Some examples of perpendicular lines in nature are even ground and the stalks of plants, which often form a perfect right angle. Another example is a waterfall, with the falling water as one line and the body of water at the bottom as the other line, which again form a right angle.
Some examples are: circle, square, rectangle, right angle triangle, equilateral triangle

If a right angle triangle has an interior angle of 30 degrees then the other two angles must be 90 degrees and 60 degrees.
Shelf brackets, cheese wedges, door stops, folded napkins Because is a triangle in which one angle is a right angle or a 90-degree angle.
You can measure it. Or you can measure some other quantities (for examples, the lengths of the sides of a triangle), and calculate the angle using trigonometry.
