Question

P (-6,0), Q (-3,-4) and R (-3,1) are three points. Show that PQ=QR​

Answer 1

see below

Explanation:

basically it's asking you the triangle long side if they r the same

PQ length: need to know the diff b/w 2 x's n 2y's

-3+6 = 3

-4-0=-4

so 3²+4² =5² - you should memorize this.

QR length - same thing

-3+3=0

1+4=5

so 0²+5² =5²

Same. done.
