An acute angle is an angle that measures less than 90 degrees, but more than 0 degrees. Think of it as a small, sharp corner. Identifying acute angles is a fundamental skill in geometry and helps us understand the shapes and structures around us. Get ready to sharpen your angle-detecting skills!
Match the terms with their definitions:
| Term | Definition |
