  1) ΔCBA ~ ΔCQR

  2) ΔCDE ~ ΔCTS

Step-by-step explanation:

In both cases, the vertical angles at C are congruent. The marking shows an additional internal angle is congruent, so the triangles are similar by the AA similarity postulate.

The vertex at C is named first, followed by the marked angle in each of the given similarity statements. The same order must be used for the vertices in the similar triangle.

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
