A triangle has angles $40^\circ$, $40^\circ$ and $x$. What is $x$, and what type of triangle is it?

The exterior angle of a triangle is $120^\circ$. The two opposite interior angles are $x$ and $70^\circ$. Find $x$.

The angles of a quadrilateral are $90^\circ$, $85^\circ$, $95^\circ$ and $y$. Find $y$.

Two figures are congruent. Which statement is true?

Two triangles are similar. The first has a side of $3$ cm matching a side of $9$ cm in the second. What is the scale factor from the first to the second?

Two similar triangles have a scale factor of $2$. A side in the small triangle is $5$ cm. What is the matching side in the large triangle?
