===Process (How to do the activity)===
−
How to do the different steps of the activity?
+
* Two equal chords are drawn, the endpoints are joined to the center of the circle to form triangles.
−
 
+
* What can you say of the angles subtended by the two chords? How are the two subtended angles equal. Compare triangles formed.
−
What kinds of questions you can ask for that activity
+
* When is the subtended angle  the largest?
−
 
+
* If the angles subtended are equal will the chords be of equal measure?
−
What are the student follow-up activities/ questions you can give?
+
'''HW Activity :''' Draw circle, at the center draw two angles of equal measure. Mark the chords formed by the angles. Measure the lengths of the two chords. Note your observations.
