MATH ANGLES and TOPIC ANGLE PAIRS  OBJECTIVES: MATH T1.2. Angle Paisr LC1.3. Describe and Explain the relationships between angle pairs based on their measures. LO3.1. Classify different kinds of angles. FACILITATORS: Mr. John Joseph Ate | Mr. Frederick Caguioa | Ms. Kimberly D. Tayaua  ANGLE MATH An angle is formed by two noncollinear rays called sides (initial and terminal sides) that have in itial side a common endpoint called vertex. FACILITATORS: Mr. John Joseph Ate | Mr. Frederick Caguioa | Ms. Kimberly D. Tayaua  ANGLE MATH An angle divides the points on the plane into three regions: In ter io r 1. the points in the interior 2. the points in the exterior 3. the points on the ray Exter io r itself FACILITATORS: Mr. John Joseph Ate | Mr. Frederick Caguioa | Ms. Kimberly D. Tayaua  NAMING AN ANGLE MATH A Angles are named using the symbol “∠” There are three ways of naming an angle: a. Using the vertex 1 b. Using three distinct points in the angle (point on one side of the angle, S H followed by the vertex, then point on the other side of angle) ∠𝑺 ∠𝑯𝑺𝑨 c. Using a number ∠𝑨𝑺𝑯 ∠𝟏 FACILITATORS: Mr. John Joseph Ate | Mr. Frederick Caguioa | Ms. Kimberly D.

Each angle is called the complement of the other. 𝟗𝟎 FACILITATORS: Mr. John Joseph Ate | Mr. Frederick Caguioa | Ms. Kimberly D. Tayaua  SUPPLEMENTARY ANGLES MATH Two angles are supplementary if the sum of their measures is 180°. Each angle is called the supplement of the other. 𝟏𝟖𝟎 FACILITATORS: Mr. John Joseph Ate | Mr. Frederick Caguioa | Ms. Kimberly D. Tayaua  TIVIT COMPLEMENT, SUPPLEMENT MATH AC Y 1. Which is the complement of 30°? 60° 2. Which is the complement of 12°? 78° 3. Which is the supplement of 79°? 101° 4. Which is the supplement of 153°? 27° 5. Which is the complement of 45°? 45° 6. Which is the supplement of 90°? 90° FACILITATORS: Mr. John Joseph Ate | Mr. Frederick Caguioa | Ms. Kimberly D. Tayaua  CONGRUENT ANGLES MATH Two angles are congruent if they have the same measure. FACILITATORS: Mr. John Joseph Ate | Mr. Frederick Caguioa | Ms. Kimberly D. Tayaua  ADJACENT ANGLES MATH Two coplanar angles with a common side, a common vertex and no common interior point. ∠𝑫𝑩𝑨 𝒂𝒏𝒅 ∠𝑨𝑩𝑪 FACILITATORS: Mr. John Joseph Ate | Mr. Frederick Caguioa | Ms. Kimberly D.

Why is it important to understand the relationships between different types of angle pairs in real life? 2. Can you think of a scenario where misjudging the relationship between angle pairs might lead to problems in real life? FACILITATORS: Mr. John Joseph Ate | Mr. Frederick Caguioa | Ms. Kimberly D. Tayaua  “Angle pairs are like the building blocks of the world around us—knowing how they work helps you create, design, and solve anything with confidence.”
