Some of you uses the concept of aternate ngles (not taught yet) to solve angles problems. What I shared with the class was that the two angles shown above are equal if the two lines are equal. Using what you know about angles, can you explain why the angles are equal?
How to paste the picture on the blog?
ReplyDeleteIs this about interior alternate angles or exterior alternate angles?
ReplyDeletei just know it but do not know how to explain??
ReplyDeleteFor alternate angle to be equal,both horizontal lines must be in parallel.
ReplyDeleteIf you want to draw a diagram, consider this.
ReplyDeleteI used PowerPoint to draw my diagram.
Then I select the diagram, right click on it and saved it as a picture (.png). Then I added in the picture.
If that cannot be done, tell me what should I add to my diagram above to help you explain better.
I have drawn my picture on my computer. but i don't know how to add in the picture onto the blog.

ReplyDeleteOne of a pair of nonadjacent angles on opposite sides of a transversal that cuts two lines. The angles are both exterior or both interior to the two lines.
ReplyDeleteI tried uploading the picture to my blog but I can't.
Thanks Yi Ying and farah. I visited both your blogs. You have two different explanations and both are correct. I am impressed! Keep up the great work!
ReplyDeleteThe rest of 5A, do visit their blog for the explanation.
