Are the triangles Similar? (yes or no). If yes, by what
kakasveta [241]

Answer:

The triangles are not similar

Step-by-step explanation:

we know that

If two triangles are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

<em>Triangle X.Y.Z</em>

\angle X=61^o

\angle Z=90^o

\angle Y=90^o-61^o=29^o ---> angle X and angle Y are complementary angles

<em>Triangle H.G.J</em>

\angle H=90^o-34^o=56^o ---> angle H and angle J are complementary angles

\angle G=90^o

\angle J=34^o

so

X.Y.Z is a61^o-90^o-39^o triangle

H.G.J is a56^o-90^o-34^o triangle

The measure of its corresponding angles are not congruent

therefore

The triangles are not similar
