Prove that the triangle with vertices P(-4,0), Q(3,5), and R(8,-2) is a right triangle.

does this help?

Step-by-step explanation:

PR=9+4+36−−−−−−−−√=7

PQ=36+9+4−−−−−−−−√=7

RQ=1+25+64−−−−−−−−−√=98−−√

PQ2+RQ2=49+49=98

segment bisector

step-by-step explanation:

line segment bisector. definition: a line, ray or segment which cuts another line segment into two equal parts. try this drag one of the orange dots at a or b and note the the line ab always divides the line pq into two equal parts.

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
