Answer

So, the measure of the third angle is $\boxed{45^{\circ}}$

Steps

Step 1 ：Given two angles of a triangle are $82^{\circ}$ and $53^{\circ}$

Step 2 ：The sum of the angles in a triangle is always $180^{\circ}$

Step 3 ：Subtract the sum of the two given angles from $180^{\circ}$ to find the third angle

Step 4 ：So, the measure of the third angle is $\boxed{45^{\circ}}$
