Answer:
Option A True
Step-by-step explanation:
we know that
The sum of the internal angles of the triangle is equal to
<u>In the triangle JKL</u>
m∠L=
so
The measurements of the angles of triangle JKL are
<u>In the triangle WXY</u>
m∠W=
so
The measurements of the angles of triangle WXY are
therefore
Triangle JKL and triangle WXY are similar by AAA ( The AAA postulate states that if you can prove that all three angles of two triangles are congruent, you can prove the two triangles are similar)
