Revolt · Accepted Answer

B: Image with description Two separate triangles are shown. In triangle C E D, C is at the top, E is at the lower left, and D is at the lower right. In triangle M P N, M is at the top, P is at the lower left, and N is at the lower right. Segments C D and M N have matching double tick marks, segments E D and P N have matching single tick marks, and right-angle markers are shown at D and N.

Question 7

Which of these triangle pairs can be mapped to each other using both a translation and a rotation about cap c ?

Revolt · Accepted Answer

B: Image with description Two separate triangles are shown, with the top triangle X Y Z positioned directly above triangle A B C. In the top triangle, vertex Y is at the peak containing a right-angle marker, while segment X Z forms a perfectly horizontal bottom base below it. Segment X Y slants upward to the right, and segment Y Z slants downward to the right. In the bottom triangle, segment A C forms a perfectly horizontal top border, while vertex B is located below it, containing the right-angle marker. Segment A B slants downward to the right, and segment B C slants upward to the right. Segments X Y and A B have matching single tick marks, and segments Y Z and B C have matching double tick marks.

Question 8

Which of these triangle pairs can be mapped to each other using both a translation and a reflection across the line containing line segment AB ?

Revolt · Accepted Answer

C: Image with description Two triangles are shown. Points X, A, Y, and B lie on the same vertical line, in that order from top to bottom. Point Z is to the left of the line, and point C is to the right. Segments X Z and A C have matching double tick marks, segments Y Z and B C have matching single tick marks, and angles Z and C have matching arc marks.

Question 9
