1. if A∨b, b∨c, then a? C. What is the reason?

2.？ The straight lines AB and CD are perpendicular to each other, the vertical foot is O, and P is a point on the straight line CD, so the distance from P to AB is _ _ _ _ _ _ _ _.

3. Known: as shown in the figure,? Yu d,? And then what? ________,? ______,? __________。

Question 3

4. As shown in the figure, straight line a∨b, then ∠ ACB = _ _ _ _ _ _

5. What is the topic of the proposition of "equal vertex angles"? The conclusion is that

Three, painting questions (8 points)

Requirements: Draw a square with a side length of 2cm, and then translate the square 4cm at 60 northwest and 4cm east respectively before drawing the figure. (Traces of drawings are required to be preserved)

Fourth, solve the problem (14'+13'+13')

1, as shown in the figure, ∠ A = 60, DF⊥AB in F, DG∨AC in AB in G,

DE∨AB crosses AC to E. Find the degree of ∠GDF.

Solution: ∵DF⊥AB (? ? )

∴∠DFA=90(？ ? )

∫DE∫AB()

∴∠ 1==( ? )

∠EDF= 180 -∠DFA

= 180 -90 =90 ( )

∫DG∑AC()

∴∠2=? =( )

∴∠GDF=-？ =?
