△GHJ and △UVW are congruent
△GHJ and △PQR are not congruent
△PQR and △UVW are not congruent.
Step-by-step explanation:
From the graph, we observe that the congruent triangles are
Because they have the same dimensions.
Based on this congruence, each answer would be

Answer:
The positive angle less than 360° that is coterminal with -215° has a measure of 145°.
Step-by-step explanation:
From Geometry, we know that angles form a family of coterminal angles as function of number of revolutions done on original angle. We can represent the set of all coterminal angles by means of the following expression:
,
(1)
Where:
- Original angle, in sexagesimal degrees.
- Coterminal angle, in sexagesimal degrees.
- Coterminal angle index, no unit.
If we know that and
, then the coterminal angle that is less than 360° is:
The positive angle less than 360° that is coterminal with -215° has a measure of 145°.
