And food is classified as chemical energy, right?
Same concept for other types of energy.
1: Find area of triangle formed by 3 points. if not zero they can form triangle.
2: Find line equation of 2 vertices and check if the 3rd vertices is present on this line. if not they can form triangle. Similarly Find the slope of the line joining points A and B,then find the slope of the line joining A and C.If they are same,then you can't draw a triangle.
Means to become interested or engaged in something. (:
