Using Corresponding Parts of Congruent Triangles

Standard

G.SRT.5 Use congruence... criteria for triangles to solve problems and to prove relationships in geometric figures.

Goals for this section:

This section is just more practice proving congruent triangles. But keep in mind all the tools you have: SSS, SAS, ASA, AAS, and Third Angles Theorem. Also, use previous things you've learned such as vertical angles and identity property.

Some tips for proof writing

Use what you've got!

When writing proofs, remember all the tools that you've been given! So think of theorems like SSS, SAS, ASA, AAS, Third Angles Theorem.
Sometimes you'll have to use other information that was taught a while ago such as Vertical Angles and Identity Property.
