Inscribed Angles (Quadrilaterals)

Inscribed Quadrilateral

All 4 angles of the quadrilateral are "inscribed" angles.

What's so special about inscribed quadrilaterals?

If a quadrilateral is inscribed in a circle, then both pairs of opposite angles are supplementary. (That means they add up to 180.)

Find the value of y.

Those last two problems were too easy.

Think about what equation would be needed to find the value of x in this problem.

Once you've found x, what about y?

Think about what equation would be needed to find the value of y in this problem.

How could you check to see if you're right?

What should both pairs of opposite angles add up to again?

Let's do one more together.

Find the measure of angles L and N.

Now it's your turn! Find the value of x.
