Answer 1

An acute angle measures less than 90°, a right angle measures exactly 90°, an obtuse angle measures greater than 90° but less than 180°, and a straight angle measures exactly 180°.

Step-by-step explanation:

An acute angle measures less than 90°. A right angle measures exactly 90°. An obtuse angle measures greater than 90° but less than 180°. A straight angle measures exactly 180°.

So, the matches are:

• Acute angle - 0°
• Right angle - 90°
• Straight angle - 180°
• Obtuse angle - 180°
