Given two parallel lines xy & zt. Three points A,B & C are on line xy, two points D & E are on line zt. Draw lines passing through the pairs of points. How many lines are there? (including xy & zt)
given a parallel line xy and zt. Three point A,B,C are on line xy, two point D,E are on line zt. Draws line passing through the pair of point. How many lines are there?
given 2 parrel lines xy and zt.Three point ABC are on line xy,two point DE are on line zt.Draw lines pasing throught the pair of points
Bài này mk dịch thoy chứ đa thì cần suy nghĩ
Cho haid đường thẳng song song xy và zt . có ba điểm abc trên đường thẳng xy hai điểm de trên đường zt . vẽ bao nhiêu đoưng thằng ở những điểm trên
If two angles are corresponding angles of the parallel lines and their measure are ( 5x - 7) and ( 4x + 3 ) then the measure of the first angles is ?
True or false
1. we can draw many lines passing through 2 given points
2. we can draw many lines passing through 1 given point
3. we cannot draw any line passing through 3 given points
4. two different lines can only have 1 common point
5. three different lines cannot intersect at 1 point
6. we can draw 3 different lines from 3 collinear points
7. 2 parallel lines may have more than 1 common point

If 2 angels are consecutive interior angles of the parallel lines and the measure of one is (4x - 2) and the other is (5x - 7). Find the measure of the first angle
Because 2 angles are consecutive interior angles of the parallel lines, so (4x - 2) + (5x - 7) =180\(^o\)
\(\Rightarrow9x-9=180^o\)
\(\Rightarrow9x=189^o\)
\(\Rightarrow x=21^o\)
Therefore, the measure of the first angle is \(4\cdot21-2=82^o\)
with triangle ABC, d is the line passing through B, E of AC. Via E draw straight lines parallel to AB and BC cut d at M, N. D is the intersection of ME and BC. NE lines cut AB and MC at F and K. CMR AFN triangles are in the same form as the MDC triangle
If 2 angles are consecutive interior angles of the parallel lines and the measure of one is(4x-2)o and the other is (5x-7)o.The measure of the first angle is...o.
