Are these triangles congruent? If so, tell how
SSS
Are these triangles congruent through SAS? Explain
Yes, they share the common side length of line segment BD.
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.
A pair of angles that add up to 90 degrees
What are complementary angles
Can we prove these triangles are congruent? If yes, tell how.
SAS
Are these triangles congruent through ASA? Explain
Yes (triangles share the side between the two congruent angles)
Congruent angles formed by intersecting lines
What are vertical angles?
Are these triangles congruent thru SSS? If so, write the congruence statement.
Not congruent thru SSS
Is this an example of triangle congruence through SAS?
No, triangles are not congruent through SAS.
Do we have enough information to prove that these 2 triangles are congruent?
No (angles are congruent but sides may be proportional)
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
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
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.
Are these triangles congruent? If so, tell how
ASA
In a pair of complementary angles, one angle measures 4x + 8 and the other angle measures 5x + 10. How many degrees are in each of the angles?
40 and 50
