Question
Given that m∠FHE = m∠BHG = m∠AHF = 90 in the below diagram, answer the following:
If m∠3 = 30, then m∠6 =?
- 60
- 50
- 30
- 40
Hint:
They are always equal to each other. In other words, whenever two lines cross or intersect each other, 4 angles are formed. We can observe that two angles that are opposite to each other are equal and they are called vertical angles.
The correct answer is: 30
m∠3 and m∠6 are vertical angles, so they are congruent. So, m∠6 = 30.
Hence, the correct option is A.
Vertical angles are formed when two lines meet each other at a point.
