Question

the winow sign shown below indicate the directions for the escalators at a department store.

if ( \triangle rstcong\triangle uvw ), which must be true?

( \bigcircangle r=angle u,angle s=angle v,angle t=angle w )
( \bigcircangle r=angle v,angle s=angle w,angle t=angle u )
( \bigcircangle r=angle w,angle s=angle u,angle t=angle v )
( \bigcircangle r=angle w,angle s=angle v,angle t=angle u )

Explanation:

Step1: Recall the property of congruent triangles

If \(\triangle RST\cong\triangle UVW\), then corresponding angles are equal. That is \(\angle R=\angle U\), \(\angle S=\angle V\), \(\angle T=\angle W\)

Answer:

\(\angle R=\angle U,\angle S=\angle V,\angle T=\angle W\)
