Description
"Properties of Parallel Lines" Intersecting Lines and Parallel Lines PPT Courseware 2
Properties of parallel lines:
Two parallel lines intersected by a third straight line have equal angles.
Simply put: two straight lines are parallel and have equal angles.
Two parallel lines are intercepted by a third straight line, and their interior angles are equal.
Simply put: two straight lines are parallel and their internal offset angles are equal.
Two parallel lines are intercepted by a third straight line, and the interior angles on the same side are complementary.
Simply put: two straight lines are parallel and interior angles on the same side are complementary.
Example 1. As shown in the figure: AB∥CD, AD∥BC are known. Fill in the blanks:
(1) ∵ AB∥CD,
∴∠1=_____(Two straight lines are parallel and their internal offset angles are equal.)
(2) ∵AD∥BC (known),
∴∠2=_____ (Two straight lines are parallel and their internal offset angles are equal.)
Do it
1. As shown in the figure: AB and CD are intercepted by EF, AB∥CD, ∠1=120o. Find the degrees of ∠4, ∠2 and ∠3.
Solution: ∵ AB∥CD
∠1＝120o
∴ ∠4= ∠1 =120o
∠2= ∠1＝120o
∠3=180°- ∠1= 180°-120°=60°
2. As shown in the figure, it is known that DE∥BC and CD are the bisectors of ∠ACB,
∠ACB=40°, then ∠EDC equals .
3. If two parallel lines are intercepted by a third straight line, then a set of bisectors of the same angle are mutually ( )
A.Perpendicular B.Parallel C.Coincident D.Intersection
4. As shown in the figure, CD∥AB, OE bisects ∠AOD, OF⊥OE, ∠D=50°, then ∠BOF is ( )
A.35° B.30° C.25° D.20°
5. As shown in the figure, AB∥CD, then ∠A+∠E+∠F+∠C is equal to ( )
A.180° B.360° C.540° D.720°
6. As shown in the figure, AB∥EF∥CD, EG∥BD, then
The angles in the figure that are equal to ∠1 (except ∠1) have a total of ( )
A.6 B.5 C.4 D.3
