Perimeter Perimeter of a square Area of a square Area of a triangle
What is the measure of the distance around a polygon called? P = 4s Is the formula to find what? Perimeter of a square Perimeter How do you find the perimeter of any object? A = s2 Is the formula to find what? Add up all of the sides Area of a square A = ½bh Is the formula to find what? In the following triangle which is the height? 10 in 7 in 8 in. 8 in. (must be perpendicular to the base) Area of a triangle In the formula A = s2, “s” stands for what? In the formula A =1/2 bh, what do you actually do with multiplying by 1/2?

About 5 doors About 2 ½ windows (closer to 3 windows) (Pi)
Find the area A = lw A = 10 x 15 A = 150 ft2 Find the perimeter P= P = 60 About 5 doors 1 way: Find the length and width of the whole figure: 16 cm high and 12 cm wide Then find the area of a rectangle A=lw A = 16 x 12 = 192 cm2 Or 2nd way: Find the area of one small square and then multiply by the number of squares that make up the figure. A=s2 A= 42 = 16 cm2 then 16 x 12 = 192 cm2 About 2 ½ windows (closer to 3 windows) (Pi) Approx or 22/7 3.14 or 22/7 Find the perimeter of a rectangle P = P = 36 in. How much carpet will you need for a rectangular room in your house that measures 10 ft x 15 ft? You want to decorate a frame with ribbon, how much ribbon would you need if the frame measures 8 in by 10 in? You have an equilateral triangular garden that needs fencing, how much fencing will you need if one side measures 20 ft? What is the area of the whole figure? 4 cm About how many doors would equal the length of the wall? About how many windows would equal the length of the wall? What is the ratio of the circumference and the diameter of any given circle? What is the approximate value of ?

radius 50.24 ft2 Area of a circle 6.28 ft protractor Acute angle
Circumference of a circle radius 50.24 ft2 Area of a circle 6.28 ft protractor Acute angle Diameter (d) C= 2r What is this formula used to find? What is 2r = ___? What is half of the diameter called? A = r2 Is the formula to find what? What is the area of the following circle? (A = r2) 8 ft What is the circumference of a circle if the diameter is 2 ft? (C =2r) What is the tool called that is used for measuring angles? What is the name of an angle that measures between 0o and 90o?
10
Obtuse angle Acute triangle Right angle
Obtuse triangle Right triangle False (if you have 2 right angles than that equals 180o so therefore there is no degrees left for the 3rd angle since the sum of the 3 angles of a triangle are to equal 180 o) (since the sum of the 3 angles of any triangle equals 180 therefore only one angle can be more than 90o) 45o angle Right angle What is the name of an angle that measures between 90o and 180o? What is the name of an angle that measures 90o? What type of triangle has three acute angles? What type of triangle has one 90o angle? What type of triangle has one obtuse angle and two acute angles? True or False? A triangle can have more than one right angle? True or False? A triangle can have more than one obtuse angle? What angle is half of a right angle?
