Question

Consider the following diagram where $AB$ and $CD$ are congruent arcs and chords. The measure of $\angle AOB={50}^o$. Then the value of $\angle COD=?$

• A. ${45}^o$
• B. ${50}^o$
• C. ${56}^o$
• D. ${90}^o$

Answer 1

The correct option is B ${50}^o$

In a circle with congruent chords the angles subtended at the center are also congruent.
The value of $\angle COD={50}^0$
