Answer: The order may be clockwise or counterclockwise. It is preserved during these transformations: translations, dilations, and rotations. A change in the orientation of the vertices implies a change in the orientation of the figure.

Answer:
see explanation
Step-by-step explanation:
(a)
The angle around the centre O of the circle = 360°, then
∠ AOB = 360° - 260° = 100°
Δ AOB is isosceles ( the radii OA and OB are congruent )
The altitude from O bisects ∠ AOB , thus
y = 50°
Since the triangle is isosceles the 2 base angles are congruent, so
x =
=
= 40°
(b)
∠ POR = 360° - 254° = 106°
Δ POR is isosceles (the radii OP and OR are congruent ) , then
the 2 base angles are congruent , thus
a =
=
= 37°
Answer:
identify each arc as a major arc, minor arc, or semicircle. ... arc QRS is a semicircle and has a measure of 180. ... If a set of adjacent arcs form a circle, then the sum
Step-by-step explanation:
It would equal 53 since w(5)=9(5)+8, which 9(5) =45 and adding 8 to it would equal 53
