PLEASE HELP!!! 1. The sides of a square 1 cm, have lines drawn between them connecting adjoining sides with their
midpoints. This creates another square within the original and this process is continued indefinitely.
(Given, Pythagoras theorem: Hypotenuse 2 = Perpendicular 2 + Base 2 )

a. Show the sequence of the sides for first 4 terms. [1]
b. Show the sequence for the areas of the squares for first 4 terms. [1]
c. Calculate the sum of the areas of the infinite squares.

One of the same side angles of two parallel lines is 20° smaller than the other one. find the measures of these two angles.
