ASVAB math tests include some questions on geometry. Often these questions will ask you to analyze lines and angles. This takes a little knowledge and some common sense. An angle is really two lines (sometimes called rays) that meet up at the same point. Angles are measured in degrees (°). Here are a few examples:
• Angles that measure less than 90° are called acute angles. Figures A and B show acute angles.
• Angles that measure greater than 90° are called obtuse angles. Figures D and E show obtuse angles.
• A right angle measures exactly 90°. Figure C shows a right angle. A right angle is often indicated by ...
