Are these triangles congruent? If so, tell how


SSS

100

Are these triangles congruent through SAS? Explain


Yes, they share the common side length of line segment BD. 


100

Are these triangles congruent? If so, tell how


No, since the congruent sides are not in the same position.

The sides are across from different angles.

100

A pair of angles that add up to 90 degrees 

What are complementary angles

200

Can we prove these triangles are congruent? If yes, tell how.

SAS

200

Are these triangles congruent through ASA? Explain


Yes (triangles share the side between the two congruent angles)

200

Congruent angles formed by intersecting lines 

What are vertical angles? 

300

Are these triangles congruent thru SSS? If so, write the congruence statement.

Not congruent thru SSS

300

Is this an example of triangle congruence through SAS? 


No, triangles are not congruent through SAS.

300

Do we have enough information to prove that these 2 triangles are congruent?


No (angles are congruent but sides may be proportional) 

300

 A pair of angles are supplementary. One angle has a measure of 2x. The other angle has a measure of 3x - 15. What is the value of x?

x = 39

400

Can you prove congruence through SSS? Explain.


You can prove congruence through SSS because the shared side length is also congruent.

Label the triangle diagram below so that you could use SAS to prove them congruent.

In a pair of vertical angles, one angle measures 7x + 17. The other angle measures 67 degrees. What is the value of x? 

x = 12

500

Do we have enough information to prove that these 2 triangles are congruent through SAS?


Yes, the third angle will be congruent. Since 2 angles are already congruent, the third one must also be congruent. Additionally, the triangles share the third side length.
