12. C ends up where A is, at (3, 3).
13. Straight across is 180°.
14. Following one point through this translation leads you to triangle KLM.
15. Since P is 3 units right of x = -3, it will end up 3 units left of it, at -6. As it's 4 units down from y = 4, it will end up 4 units above it, at 8. (-6, 8)
16. It appears to be the same as a translation (it's flipped twice and ends up in the same orientation).

asap If a figure has been dilated by a scale factor of 2, which transformation could be used to prove the figures are similar using the AA similarity postulate? A reflection to map at least two sides of the image to two sides of the pre-image. A series of dilations to map at least two angles of the image to two angles of the pre-image. A rotation to map at least two sides of the image to two sides of the pre-image. A series of translations to map at least two angles of the image to two angles of the pre-image.

Step-by-step answer

A series of translations to map at least two angles of the image to two angles of the pre-image.

Step-by-step explanation:

we have 2 figures: △ABC and △A′B′C′

△A′B′C′ is the dialation of △ABC

we have to prove that the figures are similar using AA similarity

AA = (Angle-Angle)

Option D is correct.

Mathematics

two triangles are shown to be congruent by identifying a combination of translations, rotations, or reflections that move one figure onto the other. if δtop ≅ δcat, which angle must be congruent to ∠tpo? why? a) ∠act because the triangles are isosceles. b) ∠cta because the triangles are isosceles. c) ∠act because corresponding parts of congruent triangles are congruent. d) ∠cta because corresponding parts of congruent triangles are congruent.

D)

Step-by-step explanation:

∠CTA because corresponding parts of congruent triangles are congruent.

The definition of congruent triangles says the corresponding parts of congruent triangles are congruent (CPCTC). Since ΔTOP ≅ ΔCAT, ∠TPO corresponds to ∠CTA.

Option B

Step-by-step explanation:

we know that

If two triangles are congruent, then its corresponding sides and corresponding angles are congruent

If triangle ACB is congruent to triangle PRQ

then

AC≅PR

CB≅RQ

AB≅PQ

∠A≅∠P

∠C≅∠R

∠B≅∠Q

therefore

∠C≅∠R

Because corresponding parts of congruent triangles are congruent

Step-by-step answer

In the given question,

Δ MOP ≅ Δ CUP

so, ∠MPO ≅ ∠CPU

Step-by-step explanation:

As when we write Δ ABC ≅ Δ DEF (1)

it means that the points are taken in such an order that the congruent sides and angles can be easily found from the notation, i.e., if we take sides and angles from the notation of RHS in the same order as those taken from the notation in LHS, then the corresponding sides and angles will be congruent.

e.g., from (1)

∠ACB ≅ ∠DFE

but, ∠ ABC is not congruent to ∠ EDF

and,

AB ≅ DE but, AC is not congruent to EF.

Now, in the given question,

Δ MOP ≅ Δ CUP

so, ∠MPO ≅ ∠CPU
