Answer 1

Your answer ⬇️

A straight line triangle representation (SLTR) of a planar graph is a straight line drawing such that all the faces including the outer face have triangular shape.

Make a right angled triangle with sticks . Hold the triangle vertical with one of the sides of right angle touching the base. Now you see from top then you see only two lines one above other third line as a point. Two lines and perfect triangle!!!
