IV. PROCEDURES
A. Reviewing
previous Lesson or Answer the following questions.
presenting new lesson 1. What do you call the figure formed when two rays
meet a common endpoint?
2. What do you call the common endpoint of the two rays
in an angle?
3. What is the unit used to measure the
size of an angle?
4. What is an angle?
B. Establishing a
purpose for the lesson Types of Angles
Acute (>0, <90 degrees)
The internal measurement of two straight lines, where the
angle measures more than 0 but less than 90°.
Right (90 degrees)
A right angle is equal to 90°
Obtuse (>90, <180 degrees)
The internal measurement of two straight lines, where the
angle measures more than 90° but less than 180°.

angle.
2. The common endpoint of an angle is called vertex.
3. Angles are named using capital letters.
4. The two rays are the sides of an angle.
