Please check the state oak to see the garbage cover reed box, no please sail and next to me.

Satisfaction to remember.

o(oThank you!)

Birdman is slow to death, so now I don't look at it.

Good things should be boiled slowly.

I guess I was always worried about being pitted by myself, so I was very careful when I wrote.

Out of the slow, there is no out today.

I'm waiting, bear with me.

It's so slow that it's going to die, you see what the fight is wrong in this chapter.

The opposite side is a birdman, slow to die, so now I don't look at it, hey... He doesn't write, and I can't help you get the latest chapters, isn't it???

I watch it every day, but it's too slow, and I think it's good to have 3 episodes a day.

The book was published on **Reading.com, and the latest chapter, of course, is where. You can go there to find the author QQ

Hello! This question is a bit of a loophole.,The time is not the same.,The number of updated chapters is definitely not the same.,By July 3, 2010 at 23:00 as of the end of mortal cultivation of immortals, there are eight volumes.,It's been updated to 1327 chapters (giant beasts, weirdos).,It's over.。

Thank you

Chapter 1321: Recapture the Spirit Land.

Volume 8 First Entry into the Spirit Realm Chapter 1321 (Updated on: 2010-06-29 06:44).

Volume 8 The First Entry into the Spirit Realm Chapter 1331 The Sky Thunders into Trees.

Volume 8 First Entry into the Spirit Realm Chapter 1323 Xuantian Fruit.

Volume 8 The First Entry into the Spirit Realm Chapter 1321 Recapture the Spirit Land.

I like to watch it, and there is no plot at all, it's the old fighting method, and it's not interesting to fight monsters, forget the big brother, you can change the plot, no, I'll always be with you, I have to give me the book, and I have to top it.

The strategy of the founding of the country (jade, the box of the national character is omitted) Feng'er sticks out his tongue (brother, the wind takes the child's word, sticks out the tongue - the head of the tongue spits out the leftovers, mouth + er = brother) take advantage of the unpreparedness of people (it should be unprepared, for the obedient) Wave goodbye (army, hand farewell) one-eyed dragon (province is missing an eye, the eye is also called the eye, and the less below plus an eye is the province. The riddle of the cyclops is "province").

I hope mine can satisfy you, and if you are satisfied, remember to praise it.

Where's your mailbox?? Forget it, you contact me, I'll send you and tell me what book you want.

Trapezoidal class:

1. Pages 106-107 of the self-study textbook, with clear objectives:

1. Master the relevant concepts and properties of trapezoids.

2. The relevant classification of trapezoids.

Learning Focus] The nature of the trapezoid.

Study the textbook and interpret the objectives (complete the following preparatory assignments):

1. Recall: The nature and determination of parallelograms? The properties and judgments of rectangles, diamonds, squares?

2. Definition of trapezoidal Make a trapezoid underneath. Indicates the height of the base (upper bottom, lower bottom) of the trapezoid, and the area formula of the trapezoid.

3. What special trapezoids have you learned? And draw one. What are the properties to observe? Use what you've learned to prove the conclusions you've reached.

1) The two base angles on the same base edge of an isosceles trapezoid are equal.

2) The two diagonals of the isosceles trapezoidal are equal.

Question: Are there any other properties of isosceles trapezoid? What should be done to understand its nature?

3) Analyze and explain the 107-page example 109-page exercise

Summary: Common methods to solve trapezoidal problems:

1) "Translational waist": divide the trapezoid into a parallelogram and a triangle (Fig. 1);

2) "Make Height": Make the two waists in two right triangles (Fig. 2);

3) "Translate diagonals": make two diagonals in the same triangle (Figure 3);

4) "Waist extension": construct two isosceles triangles with common angles (Figure 4);

5) "Equal area deformation", which connects one end of the upper bottom of the trapezoid with the other waist midpoint, and extends to the point where it intersects with the extension line of the lower bottom to form a triangle (Fig. 5).

3. Consolidate exercises to achieve goals (cooperation, problem solving):

1. In trapezoidal ABCD, AD BC, B=30 degrees, C=45 degreesAD=AB=8cm, find the length of waist CD and lower bottom BC.

In a right-angled trapezoidal ABCD, AD BC, AB BC, E are the midpoints of the CD, then ABE is

A, isosceles triangle B, right triangle C, isosceles right triangle D, equilateral triangle.

3. In trapezoidal ABCD, AD BC, then A: B: C: D may be

a、3:5:6:4 b、3:4:5:6 c、5:4:6:3 d、6:5:4:3

4. The following propositions are false propositions

a. The two diagonals of an isosceles triangle are equal b. A quadrilateral with equal diagonals is an isosceles triangle.

c. An isosceles triangle is an axisymmetric figure d. The sum of the two bases of the trapezoid is less than the sum of the two diagonals.

5. Isosceles trapezoidal middle and upper bottom: waist: lower bottom = 1:2:3, then the degree of the lower bottom angle is

6. In trapezoidal ABCD, AD BC, AD=8m, BC=17m, C=70 degrees, B=55 degrees, find the length of BC.

Verification: CE=(ab+cd).
