الهندسة والقياس: الزاويتان المتكاملتان

The video tutorial explains the concept of angle sums in triangles, focusing on complementary angles. It demonstrates how the sum of two angles equals the measure of a third angle, which is 180 degrees. The tutorial further defines complementary angles as those whose measures add up to 180 degrees. An example is provided where one angle is known, and the other is calculated using the complementary angle property. The video concludes with a recap of the key points discussed.
