Question 5 • CMS 2026-2027 NC Math 2 CREDIT RECOVERY
Which of these triangle pairs can be mapped to each other using a single reflection?
Answer
A
Image with description Two separate triangles are shown, with triangle L M N above triangle E F G. In triangle L M N, L is the left vertex, M is above and to the right of L, and N is to the right and slightly below L. In triangle E F G, E is the left vertex, F is below and to the right of E, and G is to the right of E. Segment L M and segment E F have matching single tick marks. Segment L N and segment E G have matching double tick marks. Angles L and E have matching single arc marks.
B
Image with description Two separate triangles are shown, with triangle E F G above and left of triangle L M N. In both triangles, the marked angle is at the upper-left vertex. From the marked angle, the single-tick side slants down, and the double-tick side extends to the right. Segment E F and segment L M have matching single tick marks. Segment E G and segment L N have matching double tick marks. Angles E and L have matching single arc marks.
C
Image with description Two triangles, E F G and L G M, share vertex G. Triangle E F G is above and left of G, with E at the upper left and F below E. Triangle L G M is below G, with L at the lower left and M at the lower right. Segment E F and segment L M have matching single tick marks. Segment E G and segment L G have matching double tick marks. Angles E and L have matching single arc marks.
D
Image with description Two triangles, E F G and L F G, share side F G. Point E is above and left of side F G, and point L is below side F G. Segment E F and segment L F have matching single tick marks. Segment E G and segment L G have matching double tick marks. Angles E and L have matching single arc marks.
