Lesson 5 - Triangles: Introduction to Trigonometry in Taglish
Lesson 5 - TRIANGLES
Bago natin suungin ang aralin tungkol sa triangle o trianggulo na siyang pinakabasehan ng Trigonometry, alalahanin nating muli ang ating mga napag-aralan na:
• An angle is formed by two rays with a common endpoint. The two rays are called the sides of the angle and the common endpoint is called the vertex.
• Angles are usually named using three capital letters of the English alphabet. But they can also be named using numbers or letters of the Greek alphabet.
• A protractor is an instrument used to measure an angle. The units of measurement for angles are degrees (°) or radians (r).
• Angles are classified according to their measurements.
• Acute angle — an angle whose measurement is less than 90°.
• Right angle — an angle whose measurement is exactly 90°.
• Obtuse angle — an angle whose measurement is more than 90°
but less than 180°.
• Straight angle — an angle whose measurement is exactly 180°.
• Reflex angle — an angle whose measurement is more than 180°
but less than 360°.
• If the sum of the measurements of two angles is 90°, they are complementary angles.
• To find the measurement of the complement of a given angle, subtract the measurement of the given angle from 90°.
• If the sum of the measurements of two angles is 180°, they are supplementary angles.
• To find the measurement of the supplement of a given angle, subtract the measurement of the given angle from 180°.
After learning all about angles in the previous lesson, you are now ready to tackle more complicated figures such as triangles. This lesson will focus on the different kinds of triangles. The knowledge you will gain from this lesson will hopefully help you in solving real-life problems.
Matapos mong malaman ang lahat tungkol sa mga anggulo sa nakaraang aralin, handa ka na ngayon upang harapin ang mas kumplikadong mga pigura tulad ng mga triangles. Ang aralin na ito ay magtutuon sa iba't ibang mga uri ng mga triangles. Ang kaalamang makukuha mo mula sa araling ito ay sana makatulong sa iyo sa paglutas ng mga problema sa totoong buhay.
Ano ang triangle?
A triangle is a polygon with three sides and three angles.
Ang trianggulo ay isang polygon na may tatlong gilid at tatlong anggulo.

LESSON 4 – SOLVING REAL-LIFE PROBLEMS USING THE PYTHAGOREAN THEOREM
Lesson 3 - Pythagorean Theorem: Introduction to Trigonometry | Trigonometry in Taglish
LESSON 3 – PYTHAGOREAN THEOREM
Sa unang dalawang leksyon ay napag-aralan natin ang tungkol sa mga uri ng linya at mga uri ng anggulo o salikop. Ngayon naman, nakatakda nating alamin ang Pythagorean Theorem at paano ito makatutulong upang lalo pa nating maunawaan ang Trigonometry.
Bago ito, alamin muna natin kung ano ang sinasabing complementary at supplementary angles.
