Question

Name all the possible angles you can find in the following figure. Which are acute, right, obtuse and straight angles?

Answer 1

∠AOB= STRAIGHT ANGLE

∠AOE =∠EOB RIGHT ANGLE

∠AOF=∠FOE=∠EOD=∠DOC=∠COB=∠DOB ACUTE ANGLE

∠BOF=∠AOD=∠AOC OBTUSE ANGLE

Answer 2

Answer:

Number of angles is 15.

Step-by-step explanation:

See the given figure.

We have 15 angles in the figure, namely,

angle BOC, angle BOD, angle BOE, angle BOF, angle BOA

angle COD, angle COE, angle COF, angle COA

angle DOE, angle DOG, angle DOA

angle EOF, angle EOA  

and finally, angle FOA.

Within those, angles, right angles are angle BOE and angle EOA.

Obtuse angles are angle BOF, angle COF, angle COA, and angle DOA.

angle BOA =180 degree.

Hence, the straight line will be AOB.

All the other angles except obtuse angles, right angles, and straight line, are acute angles. (Answer)
