Question

if 2 lines intersect at a point and if one pair of vertically opposite angles are acute angles,then the other pair of vertically opposite angles are______?​

Answer 1

Answer:

Step-by-step explanation:

When two lines intersect, the sum of one angles from both the pairs of vertically opposite angles, is 180

 

Now, if one pair forms an acute angles, say θbe the acute angle.

Then the other angle formed be ϕ

hence, θ+ϕ=180

ϕ=180−θ

But, θ is an acute angle, hence ϕ is an obtuse angle.

hence, the other pair of vertically opposite angles will be formed by obtuse angles.
