Tip: The contents of the introduction should include name, native place, identity, life experience, major achievements, etc. Example: Wu Yun (469-520), born in Xing Wu (now Anji, Zhejiang), is a historian and writer. Poor family and unhappy life. His achievements in parallel prose are very high, and his parallel prose is scattered and self-willed, so he is called "Wu Junti". He is good at writing letters in parallel prose, and The Book with Zhu is a masterpiece in this respect. Most of his poems are landscape themes, with fresh and straightforward style and certain artistic achievements.

Parallel lines 1. 1 1. ∠4, ∠4, ∠2, ∠52.2, 1, 3, BC3.C4.∠2 equals ∠3. The internal angles are ∠B and ∠BCE, ∠B and ∠HAB, ∠D and ∠GAD, ∠D and ∠ DCF; The internal angles on the same side are ∠B and ∠DAB, ∠B and ∠DCB, ∠D and ∠DAB, ∠D and ∠DCB.
1.2 (1)1.(1) ab, CD(2)∠3, ∠ADE angle, two straight lines parallel to 2. Slightly 3. AB∨CD, slightly 4. It is known that ∠ B. obtains ∠ADG = 12∠ Ade, ∠ABF= 12∠ABC, then ∠ADG=∠ABF, so DG∨BF.
1.2 (2) 1. (1) 2,4, the internal dislocation angles are equal, two straight lines are parallel to (2)1,3, the internal dislocation angles are equal, and the two straight lines are parallel to 2. D3。 ( 1)a∨。 So the two straight lines are parallel. The reasons are as follows: ∠ BCD = 120, ∠ CDE = 30, you can get ∠ DEC = 90. So ∠ DEC+∠ ABC = 180. AD； BC(2)AB and CD are not necessarily parallel. If the condition ∠ ACD = 90 or ∠ 1+∠ D = 90 is added, it can be said that AB∨CD6. Abd is known as ∠Abd+∞.
1.3( 1) 1 . D2 .∠ 1 = 70，∠ 2 = 70，∠ 3 = 1 10 3。 Known; Two straight lines are parallel and the same angle is equal; 305.β = 44.∫ab∨CD, ∴ α = β 6. (1) ∠ B = ∠ D (2) X = 65443 from 2x+15 = 65-.
1.3 (2)1.(1) Two straight lines are parallel and have the same angle. (2) Two straight lines are parallel, and the internal dislocation angle is equal to 2. (1) × (2 )× 3. (1) dab (2) Two straight lines are parallel). ∴∠ 4 = ∠ 3 = 120 (two straight lines are parallel and equal to the complementary angle). 5. yes. Like 6. ∠APC=∠PAB+∠PCD。 Reason: AC, then ∠ BAC+∠ ACD = 180. ∴∠PAB+∠PCD = 180-∠cap-∠ACP . 10(65438

Second, fill in the blanks
1 1.3 12. 13.- 1 14.=
3. 17. The other root of the equation is that the value is 4.
18. Because a+b=2++2-=4 and a-b=2+-(2-)=2, ab=(2+)(2-)= 1.
4. 19. solution: let the total output of crop straw in our province be a and the growth rate of rational utilization be X. from the meaning of the question:
30%a( 1+x)2=60%a, that is, (1+x)2=2.
∴x 1≈0.4 1, x2≈-2.4 1 (it doesn't matter).
∴x≈0.4 1。
In other words, the annual growth rate of rational utilization of straw in our province is about 4 1%.
20. Solution: (1)∵ The equation has a real root ∴ δ = 22-4 (k+ 1) ≥ 0.
The solution shows that k≤0, and the range of K is k≤0(5 points).
(2) According to the relationship between the root and the coefficient of a quadratic equation, X 1+X2 =-2, X 1x2 = K+ 1.
x 1+x2-x 1x 2 =-2+k+ 1
From what is known, -2+k+ 1-2.
And (1)k≤0∴-2.
∫k is an integer ∴, and the values of k are-1 and 0. (5 points)
5.2 1.( 1) The solution can be drawn from the meaning of the question.
∴(3 integral)
And point A is on the function, so we have to solve the equations.
So the coordinate of point B is (1, 2)(8 o'clock).
(2) When 02, y 1
When1y2;
When x= 1 or x=2, y 1=y2. (12 points) 7. 22. Solution: (1) If the width is x meters, then: x(33-2x+2)= 150.
Solution: x 1= 10, x2=7.5.
When x= 10, 33-2x+2 = 15.
When x=7.5, 33-2x+2 = 20 >; 18, irrelevant, give up.
∴ Chicken farm length15m, width10m. (5 points) (2) If the width is x meters, then: x(33-2x+2)=200,
That is x2-35x+200=0.
δ=(-35)2-4×2×200 = 1225- 1600 & lt； 0
The equation has no real number solution, so the chicken farm area can't reach 200 square meters. (9 points)
(3) When 0
When 15 ≤ A
When a≥20, two rectangular chicken farms with different lengths and widths can be enclosed; (12)
