Question

Write the answers to the following questions with reference in the given figure.

1. Write the name of the opposite ray of ray RP.
2. Write the intersection set of ray PQ and ray RP.
3. Write the union set of ray PQ and ray QR.
4. State the rays of which seg QR is a subset.
5. Write the pair of opposite rays with common end point R.
6. Write any two rays with common end point S.
7. Write the intersection set of ray SP and ray ST.

Answer 1

1. Ray RS or ray RT, ray RP are opposite rays. 
2. The intersection set of ray PQ and ray RP is ray PQ.
3. The union of line PQ and line QR is the set line RQ.
4. Line QR is a subset of ray RQ, ray SQ, ray TQ… etc subset.
5. Point R is the common origin for the opposite ray s, ray RP (RQ) and ray RS (RT).
6. The names of two ray S pair with starting point S are ray SR and ray ST.
7. The intersection set of ray SP and ray ST is S.
