B. The number of times u can rotate the figure so it looks like itself (2)
Answer:
At least two congruent sides
At least two congruent angles
At least one segment that is an angle bisector, while also being a median, while also being a perpendicular bisector, while also being an axis of symmetry.
Step-by-step explanation:
Where R is the median between Q and L:
From my understanding of a triangle's centroid, it divides an angle bisector into parts of 2/3 and 1/3. In the given problem, these divisions are NS and SR. Therefore, twice SR would be equal to NS. From here, we can get the value of X, to solve for SR.
NS = 2SR
(x + 10) = 2(x + 3)
x + 10 = 2x + 6
x = 4
Therefore, SR = (x + 3) = 7
Pythagora: 20^2=(4x)^2+(3x^2)
400=16x^2+9x^2
x^2=400/25
x^2=16
x=4
12.5% because u just divide 50 by 4
