Points A, B and C lie on a circle, centre O.<br> Angle AOC = 142°.<br> Find the value of y.

aksik [14]

The value of the angle $y$ within the quadrilateral $OABC$ inscribed the circle is 142°.

Let suppose that quadrilateral $OABC$ is a parallelogram. Then, the following conditions must be fulfilled:

$\overline {OA} \cong \overline {BC}$
$\overline{AB} \cong \overline{OC}$
$\angle AOC \cong \angle ABC$

In addition, if we have a rhombus we have the additional condition as A, B and C lie on the circle:

$\overline{OA} \cong \overline {AB} \cong \overline {BC} \cong \overline{OC}$ (4)

If we know that $\angle AOC = 142^{\circ}$ , then the value of $\angle ABC = y = 142^{\circ}$ .

Based on all these finding, we conclude that the value of the angle $y$ within the quadrilateral $OABC$ inscribed the circle is 142°.
