Exercise 1 Page 853

Practice makes perfect
a To be sure that the canvas is a square, Jen should check if it satisfies one of the Conditions of Squares. Let's recall them.
  1. All four sides are congruent, and all angles are right angles.
  2. The diagonals are congruent and perpendicular.

If the canvas will satisfy any of the above conditions, then Jen can be sure that it is a square.

b Let's begin with recalling that in a square all sides are congruent and all angles are right angles. This means that all sides of this canvas have a length of 2 feet, and all angles have a measure of 90^(∘).

x=2 ft y=90^(∘)
