The smallest angle in a triangle has the  side opposite of it. (shortest/longest)

In the $∆XYZ$, given below, write the name of equal sides and determine the third angle ?

In $△ABC$ given below, $BC=5 \mathrm{cm}, \angle C=40°$ and $\angle B=50°$. Is $AB=AC$? If not, why?

In $△ABC$ given below, $BC=5 \mathrm{cm}, \angle C=40°$ and $\angle B=50°$. Which one is the longer side $AB$ or $AC$?

In $△ABC$ given below, $BC=5 \mathrm{cm}, \angle C=40°$ and $\angle B=50°$. Find whether the largest side is opposite to the smallest angle or to the largest angle.

If $△PQR$ has $PQ=PR$ and $\angle R=28°$. Then calculate the remaining angles.

A triangle has two sides of equal length. If the angles opposite to them are $30°$, then determine the third angle? Write the answer in degrees.

In an isosceles triangle, if the angle at the vertex is $70°$, then determine the other two angles opposite to the equal sides.

$△ABC$ is a right-angled triangle with $\angle C=90°$ and $CA=CB$. Determine $x$? Write the answer in degrees.
