Learning Objectives

1

Decompose angles into smaller component angles

2

Calculate unknown angle measures by breaking down complex angles

3

Recognize how God's design demonstrates mathematical precision

📖 Scripture Connection

Proverbs 3:19

“Yahweh by wisdom founded the earth. By understanding, he established the heavens.”

— Proverbs 3:19 (WEB)

God's mathematical precision in creation reflects the systematic way we decompose and understand angles
