The document provides a task to unscramble jumbled letters to form basic geometric words, including 'angle' as a defined term. It explains that defined terms have formal definitions and highlights the four characteristics of a good definition. Additionally, it emphasizes the importance of defining geometrical terms.

1. DEFINED TERMS
MATHEMATICS 8

2. Direction: Arrange the jumbled letters
to form a basic geometric word.
1. galne
2. YAR
3. MENTSEG
4. LLICONAER
5. PLCAORAN

3. In geometry, defined
terms are terms that have
a formal definition and
can be defined using
other geometrical terms.

4. What is the definition of the
basic geometric word:
1. Angle - is a combination
of two rays (half-lines) with
a common endpoint

10. The four characteristics of a good definition
are:
1. It names the term being defined;
2. It places the term into a set or category;
3. It distinguishes itself from other terms in
that category (without providing
unnecessary facts)
4. It is reversible.

11. Give at least 3 basic geometric
word and give its definition

12. Why it is important to
define a certain word?
