Alternate Angles
What are alternate angles?
In the applet below, a TRANSVERSAL intersects 2 PARALLEL LINES.
When this happens, there are 2 pairs of ALTERNATE ANGLES that are formed.
What do you observe about the alternate angles?
By sliding the bar, what other angle properties do you observe?
To identify alternate angles is to look for the letter Z. Can you find the letter Z in the diagram below? Use the highlighter function to highlight and indicate the angles that are the same.
Which angles are the same? You can choose more than 1 answer.
The diagram shows a pair of parallel lines and a transversal.
Which of the following pairs are alternate angles?
Find the unknown angle.
Find angle F.
In conclusion, ALTERNATE ANGLES are equal!
