All of the following are ways to prove triangles congruent except. sss, sas, asa, ssa.

Option (d) is correct.

SSA is  not a ways to prove triangles are congruent.

Step-by-step explanation:

Given : The ways to prove triangles are congruent.

We have to choose which one out of given options are not a ways to prove triangles are congruent.

Consider,

1) SSS - Two triangles are said to be congruent when all the three sides of the given triangles are same.

2) SAS - Two triangles are  said to be congruent when two sides of a triangle are same and angle between them is equal.

3) ASA - Two triangles are said to be congruent when two angles of a triangle are equal and side  is equal.

4) SSA - There is no such congruence conditions.

Hence, SSA is  not a ways to prove triangles are congruent.

(-14, -16), (-16, -16), and (-14, -20)

Step-by-step explanation:

First we see that k, the scale factor is -2, so it is enlargement. The triangles points are (7,8), (8,8), and (7,10). When you enlarge by a factor k you multiply every coordinate point by k, so the new triangles points would be (14,16), (16,16), and (14,20). Finally, the negative sign in k means that we rotate the triangle 180 degrees about the origin, and the rule for rotation of 180 degrees about the origin is (x, y) --> (-x, -y). So, the triangles points would be (-14, -16), (-16, -16), and (-14, -20).
