If in a DS geometry Q a triangle that looks like a Right triangle but does not show the 90 deg symbol
and its legs are 8 and 6 is it still a Right Triangle ?
[highlight]Sides in conjunction with Pythagorean theorem is a necessary but not sufficient condition for a triangle to be Right angled triangle.[/highlight]
What this implies is that, if the sides of a triangle are 6,8 and 10, they are a Pythagorean triplet but alone cannot guarantee that triangle to be right angled triangle.
Hope it will help.
