Other than itself, what is an angle that is congruent to ∠2?

angle 1 or 3

Step-by-step explanation:

The angle congruent to angle 2 is angle 1 and angle 3.

Angle 1 and angle 2 are supplementary angles, so they add up to 180 degrees. Because angle 1 is 90 degrees, or a right angle, that means angle 2 must also be 90 degrees. This makes them congruent.

because angle 1 and angle 3 are vertical angles, they are congruent, and because angle 1 is congruent to angle 2, then angle 1 is congruent to angle 3.

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis

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
