A 0.500 kg bead slides on a straight frictionless wire with a velocity of 1.50 cm/s to the right. The bead collides elastically with a larger 0.750 kg bead initially at rest. After the collision, the smaller bead moves to the left with a velocity of 0.70...

I guess I don't understand how to write the answer.

Angle ABC is congruent to RPQ by____? and angles ABC and RPQ are congruent by _____?
