its the first one corresponding angles

< 1 and < 3 are Corresponding Angles.

Step-by-step explanation:

Given the two parallel lines, L1 and L2, and the transveral across those two lines:

Then < 1 and < 3 are corresponding angles, since they are both on the same side of the transversal and in the same relative position. Corresponding angles are congruent, so < 1 and < 3 measure the same number of degrees.

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
