Question

∆r and ∆s are vertically opposite angle of each other ,measure of ∆r is 80° then find measure ∆s​

Answer 1

Hello, Buddy!!

||Required Response||

Given,

∠r & ∠s are Vertically Opposite Angles.

• Vertically Opposite Angles are Equal.

→ ∠r = ∠s

→ ∠r = 80°

• Value of angle r ☞ 80°

Answer 2

Answer:

The measure of $\angle s=80^{o}$.

Step-by-step explanation:

Given $\angle r$ and $\angle s$ are vertically opposite angles.

Measure of $\angle r=80^{o}$

• When two lines intersect with each other, 4 angles are formed at the vertex.
• And the angles which are opposite to each other are called vertically opposite angles.
• The measure of angle of a pair of vertically opposite angles are always equal to each other.

Since,  $\angle r$ and $\angle s$ are vertically opposite angles, the measures must be equal.

Since,  $\angle r=80^{o}$ therefore $\angle s=80^{o}$

Hence, the measure of $\angle s=80^{o}$.
