INTRODUCTION TO PLANE GEOMETRY 1 //PART1//BY ALAM

this videos gives us the intoduction to plane geometry 1 ( angle properties)
In this video, we are going to learn the various types of angles we have
1. Acute angle - less than 90
2. Right angle = 90
3. Obtuse angle - greater than 90 less than 180
4. Straight angle = 180
5. Reflex angle - greater than 180 but less 360
6. Adjacent angles - have common arm and common vertex, uncommon arm on opposite sides of the common arm
7. Complementary - two angles that sum up to 90
8. Supplementary - two angles that sum up to 180
9. Adjacent Supplementary angles - two angles that sum up to 180, have common arm and common vertex, uncommon arm on opposite sides of the common arm
10. Angles around a point = 360
11. Vertically opposite angles are equal
12. Perpendicular line
