Plot and label the following points: A: (1,1) B (4, 1) C (5, 4) D (2, 4)

Connect the points

Plot the same figure’s reflection.

A: (1,-1) B (4, -1) C (5, -4) D (2, -4)

How many faces?

How many edges?

How many vertices?

Why is this the best answer?

This is the radius of the moons orbit. It is 240,000 miles.

How do you get the circumference of the moons orbit around the earth.

X diameter

That’s 3.14 x the diameter (240,000 x 2= 480,000)

The circumference of the moons orbit around the the earth is 1,507,200

Then you divide it by 28 days because that is how long it takes for the moon to get around the earth. Which is 53,828

Then you divide that by 24 because there is 24 hours in a day

Which is 2,000 mph

Space shuttle speed 20,000 mph.

The moon needs to be 24,000 miles away from where you take off. So in 12 hours, you will land on the moon.

You divide 240,000 by 20,000

Can you make a slide like the last one, but this time travel to Mars?

Pi R squared sounds like area to me….

Mr. C.’s example for circumference

Use red construction paper to draw a circle that has a

radius of 4 inches.

Mr. C’s Examples

Use green construction paper to draw a circle that has a diameter of 4 inches.

What is the area of these triangles and parallelograms?

1 3 42 5123The width of the base

is 5

The height of the triangle is 3.

x = 15

Because every triangle is HALF of a rectangle you divide the area by 2.

15 2= 7.5
