Which shape has 4 equal sides and 4 right angles?
A Square
100
What (five-sided) polygon is this?
It is a pentagon!!
100
What is the perimeter? Is it the "outside" or the "inside?"
Also, do we add or multiply to find the perimeter??
The perimeter is the "outside."
And, we add to find the perimeter!
100
What is the area? Is it the "outside" or the "inside?"
Also, do we add or multiply to find the area??
The area is the "inside."
And, we multiply to find the area!

Find the perimeter of a rectangle with sides measuring 4 inches and 5 inches:
18 in.
200
Draw and describe parallel lines.

200
A shape with 8 sides is called
octagaon
200
What is the perimeter of this shape?
You would do 5 + 5 + 3 + 3.
This equals 16cm! Try not to forget the labels even though Mr. T does sometimes.
Remember, showing your work is very important! If you just give me an answer, you will lose lots of points on the test.
200
What is the area of the following shape?
Well, you would need to multiply 3 times 5...
So, 3 x 5 = 15 square cm
200
What is the area of this square?
The area would be 6 x 6 = 36 sq m.
300
Which shape has 4 equal sides and may have NO right angles?
A Rhombus!
300
What shape has one vertex, one edge, and two faces?
cone
300
What is the perimeter of the following figure?
Well, if you count by ones, you will see that there are six (6) rows and that there are ten (10) squares in each row.
So, 6 + 6 + 10 + 10= 32 units!
300
What is the area of the following figure?
Well, we have six rows of ten.
So, we would do 6 x 10 which equals 60 square units!!
300
What is the area of the following figure?
You would count by ones! The area is 30 square units.
400
How are these following shapes alike?
How are they different?
They are both polygons, and they are both quadrilaterals.
The top shape is a trapezoid and has ONE set of parallel lines. The bottom shape is a parallelogram and has TWO sets of parallel lines.
400
What makes this shape a rectangle? (No, not because it has four sides or is a quadrilateral. There are many shapes with four sides that are not rectangles.)
What makes it a rectangle is that it has four right angles!
400
What is the perimeter of the following shape? HINT: It is a square.
Well, since squares have four sides that are all the same length, that means that each side is 7 units.
So, 7 + 7 + 7 + 7 = 28 units!
400
Find the area. Don't forget UNITS!!
21 square inches.
400
What is the perimeter of the following figure?
The perimeter would go as follows:
4 + 3 + 3 + 2 + 2 + 6 + 1 + 1 = 22 units!
500
Draw another shape that "Fits the Rule."
What do you think the rule is?
The rule is: "It must be a rectangle."
All three shapes are quadrilaterals and parallelograms, but the two shapes that fit the rule are both rectangles (they have four right angles.)
500
Name this shape with as many names as possible. You need AT LEAST THREE names.
1.) Polygon
2.) Quadrilateral
3.) Parallelogram
4.) Rectangle
5.) Rhombus
6.) Square
500
The perimeter is 30 ft. What is the length of the missing side?
8 ft
500
What is the area of the figure below?
Well, if you break it up into three rectangles, they would look like this:
So, you would have:
4 x 2 = 8, 3 x 3 = 9, and 3 x 9 = 27
8 + 9 + 27=44 sq cm!
500
What is the perimeter AND the area for the following parallelogram?
Well, the perimeter would be 8 + 8 + 4 + 4 = 24 m.
The area would be 4 x 8 = 32 sq m.
