properties of a triangle
16. Sum of all angles of a triangle = 180°
17. Exterior angle = Sum of two opposite interior angles of it
18. Any two angles of a triangle are equal in measure then opposite sides of them are also equal in length
19. Sum of any two sides of a triangle greater than third side of it
20. Any two sides of a triangle are equal in length then opposite angles of them are also equal in measure
