<u>The question in English</u>
Observe the following triangles. Make sure they are similar.
we know that
If two angles of a triangle have measures equal to the measures of two angles of another triangle, then the triangles are similar.
so
In the triangle ABC
Find the angle C
the sum of the internal angles of a triangle is equal to 180 degrees
A+B+C=180
solve for C
C=180-(A+B)-------> C=180-(50+57)
C=73°
angle C=angle R
angle A=angle P
therefore
<u>the answer is</u>
triangles ABC and PQR are similar
