Please could someone help me with these questions sorry about the scribbling on one page I got stuck

question 4
So the polygon has 10 sides, to calculate how much all the interior angles are summed up, you have to see how many triangles you can fit into the polygon (this works for any polygon), in this case it is 8 (see file attached). Therefore you do 8 x 180 = 1440, so the overall angle is 1440º. Now you do 1440 : 10, because there are 10 equal angles, and that is 144º.
Every angle has 144º

Please help! Triangle ABC is translated by the rule (x + 1, y + 1) and then dilated by a scale factor of 2 centered at the origin. Which statement describes the properties of triangles ABC and A''B''C'' after the transformations?A) ∠C and ∠C'' are congruent after both the translation and the dilation.
B) ∠C and ∠C'' are congruent after the dilation, but not after the translation.
C) segment AC and segment A double prime C double prime are congruent after both the translation and the dilation.
D) segment AC and segment A double prime C double prime are congruent after the dilation, but not after the translation.

Answers

Answer:

Step-by-step explanation:

1) Translated figures are congruent ones, so $\bigtriangleup ABC\cong \bigtriangleup A'B'C'$ , one unit to the right and one up in comparison to $\bigtriangleup ABC\cong \bigtriangleup ABC$ .

2)Since $\bigtriangleup A''B''C''$ was dilated with a scale factor of two then It's a similar figure to $\bigtriangleup ABC$ . Similar figures have congruent angles and different sizes.

Hence, ∠C≅∠C"
