Answer/Step-by-step explanation:
A. <1 and <4 => vertical angles.
They share the same vertex/corner and are opposite each other as two straight lines intersect.
B. <3 and <5 => same-side interior angles.
They lie on the same side of the transversal and within the two parallel lines the transversal intercepts.
C. <4 and <5 => Alternate Interior Angles.
These angles lie on either side of the transversal, and within the parallel blinds cut across by the transversal.
D. <3 and <7 => Corresponding Angles.
They are found in the same side of the transversal occupying the same position.
