To determine if triangles MNO and RST are similar using the AA (Angle-Angle) similarity theorem, we need to check the angles of both triangles.
-
Find angle N in triangle MNO:
- The sum of the angles in a triangle is 180 degrees.
- In triangle MNO, we have:
- m<M = 63 degrees
- m<O = 71 degrees
- m<N = 180 - (63 + 71) = 180 - 134 = 46 degrees
-
Find angle S in triangle RST:
- For triangle RST, we have:
- m<R = 58 degrees
- m<T = 71 degrees
- m<S = 180 - (58 + 71) = 180 - 129 = 51 degrees
- For triangle RST, we have:
-
Comparing the angles of both triangles:
- Triangle MNO has angles:
- m<M = 63 degrees
- m<O = 71 degrees
- m<N = 46 degrees
- Triangle RST has angles:
- m<R = 58 degrees
- m<T = 71 degrees
- m<S = 51 degrees
- Triangle MNO has angles:
Now we can observe the angle pairs:
- Compare m<M (63°) to m<R (58°) - not equal
- Compare m<O (71°) to m<T (71°) - equal
- Compare m<N (46°) to m<S (51°) - not equal
Since not all corresponding angles are equal, we can conclude that triangle MNO is not similar to triangle RST.
Therefore, the conclusion is: No, they are not similar.
