here,
Q is the midpoint of PR.
O is the midpoint of PN.
So, the line joining the midpoints of two sides is half and parallel to the third side.
So, QO is parallel to NR.
Now,
in triangles OPQ and NPR,
i) angle OPQ = angle NPR (common angle)
ii) angle POQ = angle PNR (corresponding angles)
iii) angle OQP = angle NRP (corresponding angles)
so,
triangle OPQ is similar to triangle NPR.
(by AAA similarity)
Answer:
True
Step-by-step explanation:
You're claiming that every set is a subset of itself.
That's trivially true, because

requires that every element of A is also an element of A, which is tautologically true.
Base = 12÷2
= 6
slant height = a
a^2 = 6^2 + 8^2
a^2 = 100
a = 10 cm
Answer:
220 miles
Step-by-step explanation:
65 miles per hour for 2 hours — 65+ 65 = 130
60 miles per hour for 1.5 hours — 60 (for the 1 hour) + 30 (for the half hour) = 90
130 + 90 = 220
