Given figure is of a rhombus.
Measures of the opposite angles of a rhombus are equal.
Therefore,

Answer:
limaçon (no inner loop)
Step-by-step explanation:
The equation of a limaçon is written generically as ...
r = b + a·cos(θ)
For b=2 and a=1, this would put the flat side on the left. Rotating it 180° can be accomplished by adding or subtracting π from θ. Then the equation can be ...
r = 2 + cos(θ-π) . . . . or ...
r = 2 - cos(θ)

Answer:
(0,5) and (2,6)
Step-by-step explanation:
PQR ~ PSQ, PQS ~ QRS (edit: and PQR ~ QSR woops forgot that!). So A, B and D.
C isn't true because it's comparing an angle to a straight line.
