Two triangles are sketched on a coordinate plane using a dilation of 2, sharing the same center ordered pair at the origin. One triangle has angle measures of 34 degrees and 80 degrees.

Using the AA criterion, what would be the two corresponding angles of the dilated triangle? (1 point)
• 34 degrees and 80 degrees
• 44 degrees and 70 degrees
• 68 degrees and 160 degrees
• 17 degrees and 40 degrees

1 answer

Using the AA (Angle-Angle) criterion for similarity, we know that dilating a triangle does not change its angle measures. Therefore, the angles of the dilated triangle will be the same as those of the original triangle.

The original triangle has angles measuring 34 degrees and 80 degrees. The third angle can be determined by using the fact that the sum of the angles in a triangle is 180 degrees:

\[ \text{Third Angle} = 180^\circ - 34^\circ - 80^\circ = 66^\circ \]

The angles of the dilated triangle will also be 34 degrees, 80 degrees, and 66 degrees.

Thus, the corresponding angles of the dilated triangle are:

34 degrees and 80 degrees

So the answer is: 34 degrees and 80 degrees.
