  Page 5 A B CD 1.Opposite sides of a rectangle are parallel and have the same length. AB CD and AB = CD AD BC and AD = BC 2. All four angles of a rectangle are right angles (90°).  A =  B =  C =  D = 90°. 3. Two diagonals of a rectangle are the same length. AC = BD Based on the properties of a rectangle on above, then: A rectangle is a quadrilateral with four right angles and the length of the opposite sides are same.

  Page 6  Circumferenceof a rectangle is the length of the outer lines on the rectangle or the sum of all sides of the rectangle.  This picture shows square KLMN with the sides are KL, MN, KN, and LM.  KL = NM = p  LM = KN = l p l  Circumference of KLMN = KL + LM + NM + KN = (5 + 3 + 5 + 3) units of length = 16 units of length So, circumference of a rectangle with the length p and the width l is Circumference of a rectangle = 2p + 2l = 2(p + l)

  Page 7  Areaof a rectangle is a measure of how much area or field that is in the rectangle or the multiplication between the two sides of rectangle.  Area of KLMN = KL x LM = (5 x 3) units of area = 15 units of area So, area of a rectangle with the length p and the width l is Area of a rectangle = p x l p l

  Page 9 1. Allsides of a square are the same length. AB = CD = AD = BC 2. Square has two pairs of parallel sides and have the same length. AB CD and AB = CD AD BC and AD = BC 3. All four angles of a square are right angles (90°).  A =  B =  C =  D = 90°. 4. Two diagonals of a square are the same length. AC = BD Based on the properties of the square on above, then: A square is a rectangle that all four sides the same length. A B CD

  Page 10  Circumferenceof a square is the length of the outer lines on the square or the sum of all sides of the square.  This picture shows square KLMN with the sides (s) are KL, MN, KN, and LM.  Circumference of KLMN = KL + LM + MN + NK = (4 + 4 + 4 + 4) units = 16 units of length Generally, circumference of a square with the length of side s is Circumference of a square = s + s + s+ s = 4 x s

  Page 11  Areaof a square is a measure of how much area or field that is in the square or the multiplication between the two sides of square.  Area of KLMN = KL x LM = (4 x 4) units of area = 16 units of area So, area of a square with the length of side s is Area of a square = s x s = s2
