the angles are 80 degree and 100 degree. Method- 4:5=4x and 5x , 4x+5x=180 , 9x=180, x=180/9, x=20, therefore, 4:5= 4*20and 5*20 4:5=80 and 100

Look closely. The answer is 8. If you look at the cuts in the ribbon which looks like a V at the top, you can see the right angle by tilting your device. Same follows with the other cuts

Ans 6:

Class : Class 9
It is Eight . If you tilt the small angles you will notice that there are eight right angles

On the outside, we see 4 right angles easily. But if you turn your device 90 degrees left/right, you will see that the angle formed by the sharp edges of the figure also measures 90 degrees. It is just not visible due to the angle you look at it.

Ans 21:

Class : Class 5
It should be 4

Ans 22:

Class : Class 6
I think soumyaraj Roy is correct as there are no other angles that are exactly 90 degrees.

Very good Nilarka Pahari and Khushie. Friends , the correct answer is B only. Just try to see . Tilt your head to your right and try to see the cuts at the end of the ribbons . You will find the error of your own. Did you find that? I know that only 5 to 37 percent of you can nfind the eight angles. Be very accurate and intelligent. I also did the same mistake while giving the test . Please look carefully!

Ans 32:

Class : Class 8

No, it is 8. You can see 4 of them easily. The other four are hidden between the sharp edges of the figure. Tilt it 2 find out.
