Answer 2

Answer:

(a) $\angle Q O Y=$ acute angle.

(b) $\angle Y O P=$ obtuse angle.

(c) $\angle R O X=$right angle.

(d) $\angle Q O X=$ reflex angle.

(e) $\angle \mathrm{POQ}=$ straight angle.

Step-by-step explanation:

(a)$\angle Q O Y=$ acute angle.

• An acute angle is an angle that measures less than 90 degrees.

(b) $\angle Y O P=$ obtuse angle.

• An obtuse angle is an angle that is greater than 90 ° and less than 180 °.

(c) $\angle R O X=$ right angle.

• All right angles are the same. All right angles correspond to a quarter of a complete turn.

(d) $\angle Q O X=$ reflex angle.

• A reflex angle is an angle that is more than 180 degrees and less than 360 degrees.

(e) $\angle \mathrm{POQ}=$ straight angle.

• A straight angle is an angle, whose vertex point has a value of 180 degrees.
• Basically, it forms a straight line, whose sides lie in opposite directions from the vertex.
• It is also termed as “flat angles”
