Two triangles are shown to be congruent by identifying a combination of translations, rotations, or reflections that move one figure onto the other. if triangle acb is congruent to triangle prq, which angle must be congruent to

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

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
