Fill in the Blank Triangle Proofs

Given the image, mark all true statements

• ∠SEO ≅ ∠STZ

• EO ≅ TZ

• SO ≅ SZ

• ∠ESO ≅ ∠TZS

• ∠YTE ≅ ∠YES

You are trying to prove triangles A and B congruent. In the Given Statement, you were told that Triangle C and D are congruent. What is the reason you would mark the blue single and blue double marked line segments congruent?

• Corresponding Parts of Congruent Triangles are Congruent.

Use the congruency statement to answer the following: 
<F = ___

• <H

• <I

• <G

• not congruent to another angle

Are these triangles congruent? If so, state the rule which you used to determine congruence.
