Answer 1

Hope it will help you alot

Answer 2

As per my opinion angles are more challenging because an angle is formed by using two lines, when two lines intersects each other an angle is formed and is symbolically represented by ∠. whereas a line is nothing but a ray which has no end point and do not have any dead end , its length is infinite.The angle properties of lines are: Vertically opposite angles are equal, for example a = d, b = c. Adjacent angles add to 180o, for example a + b = 180o, a + c = 180. Corresponding angles are equal, for example a = e, b = f, c = g, d= h.
