Answer 1

T is a right angled triangle (proof:: Pythagoras theorem). U has two equal angles and that means it's two sides are equal and it has one angle equal to 90.. So, U is both a right angled and isoceles triangle...V is just an isoceles triangle having 2 sides equal.. W is also an isoceles triangle ...Here it goes..
