Answer:
Angles of rotation that produce symmetry are the angles that we can rotate the image, and the end result will be the starting image. (the angles are always measured from the x-axis)
Here we can clearly see that in each quadrant we have a petal of the flower.
Then the angles that change one quadrant into other quadrant will produce symmetry.
Those angles are:
90°, 180°, 270°, 360°, etc.
We can define the set of those angles as:
A {n*90° I n ∈ Z}
Answer:
90°
Step-by-step explanation:
sum the parts of the ratio 2 + 6 + 8 = 16
The sum of the 3 angles in a triangle = 180°
divide 180 by 16 to find the value of one part of the ratio.
= 11.25° ← 1 part of the ratio
8 parts = 8 × 11.25° = 90°
The largest angle in the triangle is 90°
