Answer:
A. It has reflectional symmetry
B. It is symmetrical
D. It has five lines of symmetry
Step-by-step explanation:
we know that
A regular pentagon has 5 sides and 5 lines of symmetry. The number of lines of symmetry in a regular polygon is equal to the number of sides
Every regular polygon has reflectional symmetry
Regular polygons are symmetrical
therefore
A. It has reflectional symmetry ------> Is true
B. It is symmetrical -----> Is true
C. It has exactly one line of symmetry ----> Is false
D. It has five lines of symmetry -----> Is true
Answer:
pretty sure it is 1.8478125
Step-by-step explanation:
Okay the points given are -4,-5 and -2, 1
we know the formula
y2 - y1/x2 - x1
label -4 as x1 and -5 x2
-2 as y1 and 1 as y2
1 - -2 turns into 3
-5 - -4 turns into -1
sp its - 3/ 1
Answer: 1/6
Step-by-step explanation: There are 4 primes. So the probability for the first draw is 4/9. Since the card is not replaced, the second probability is 3/8. 3/8 * 4/9 is 12/72, which simplifies into 1/6.
