*'''Prerequisites/Instructions, if any''' :  <br>
*Process/ Developmental Questions
+
#The students should have prior knowledge of parallel lines , transversal, angles and types of angles formed when a pair of parallel lines are intersected by a transversal.
*Evaluation
+
#They should know what the terms interior, exterior, adjacent, alternate, consecutive, congruent, linear and corresponding mean.
*Question Corner
+
#Students should know the definition of complementary angles, supplementary angles, and congruent angles.

*'''Process''': <br>
 +
#Reiterate that when a transversal  intersects parallel lines, several pairs of congruent and supplementary angles are formed.
 +
#Have students draw two parallel lines and a third line(transversal) intersecting those two lines on their own paper. Direct them to think about any angle relationships they see. Have them discuss their conjectures with a partner.
 +
#The teacher can next  project the GeoGebra worksheet and discuss about types of angles and their relationships with the class .
 +
#Finally the teacher and students can summarize together the angle relationships.<br>
 +
Linear pair of angles - adjacent and supplementary<br>
 +
Vertical angles - congruent<br>
 +
Corresponding angles -congruent<br>
 +
Alternate interior angles - congruent<br>
 +
Same side interior angles - supplementary<br>
 +
Alternate exterior angles - congruent<br>
 +
Same side exterior angles - supplementary<br>
 +
 
 +
*'''Developmental Questions (What discussion questions)'''  : <br>
 +
#How many pairs of corresponding angles are there ?
 +
#What is true about corresponding angles formed when parallel lines are cut by a transversal?
 +
#Compare different pairs of alternate interior angles. What do you notice?
 +
#<EGD and <AHF are alternate exterior angles. What is another pair of alternate exterior angles?
 +
#Compare different pairs of same-side interior angles. What do you notice?
 +
#Compare different pairs of same-side exterior angles. What do you notice?
 +
 
 +
*'''Evaluation (Questions for assessment of the child)''' : <br>
 +
#What are the characteristics of linear angles (adjacent and supplementary) ?
 +
#What do you observe about the angle measures of the linear angles?
 +
 
 +
*'''Question Corner''' :
 +
#What do adjacent , alternate, linear , corresponding and consecutive mean individually
 +
#What are complementary angles?
 +
#What are supplementary angles ?
 +
#What does it mean if two angles are congruent?
 +
#What is the complement of 65 degrees
 +
#What is the supplement of 70 degrees?
 +
#Compare angle relationships formed by parallel lines vs. angle relationships formed by non-parallel lines.
