How to determine two acute adjacent angles from a figure

The video tutorial explains how to identify acute angles and adjacent angles in a geometric figure. It emphasizes the importance of labeling angles correctly using three points. The teacher discusses the properties of adjacent angles, which share a common side and vertex, and guides students in identifying acute angles that are less than 90 degrees. The tutorial concludes with a clarification on angle measurements and a review of the concepts covered.

Explain why angles FKG and GKJ are considered acute and adjacent.

If angle FKJ is 90 degrees, what can you infer about the angle HKJ?
