two triangles are shown to be congruent by identifying a combination of translations, rotations, or reflections that move one figure onto the other.
if δcat ≅ δdog, which line segment must be congruent to ct? why?
a) do because the triangles are isosceles.
b) ca because the triangles are isosceles.
c) dg because corresponding parts of congruent triangles are congruent.
d) og because corresponding parts of congruent triangles are congruent.

C) DG because corresponding parts of congruent triangles are congruent

Step-by-step explanation:

CPCTC :- It is a Property of congruent triangles that says that the corresponding parts of congruent triangle are congruent.

Given : ΔCAT ≅ ΔDOG

Then the corresponding parts of both triangle are congruent.

i.e. corresponding sides of both triangle are congruent.

Since CT is corresponding to DG.

Then, CT  is congruent to DG .

Hence, the correct answer is C) DG because corresponding parts of congruent triangles are congruent.

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
