Answer:
B. (x, y) → (-x,-y)
This rule is given triangle is reflection about origin or
Rotation clockwise or counter clock wise with 180°
Step-by-step explanation:
<u>Explanation:-</u>
A triangle has coordinates at X(3,7),Y(6,7) and Z(4,2)
The Rule ( x, y)→ ( - x, -y)
<em>This rule is given triangle is reflection about origin or Rotation clockwise or counter clock wise with 180°</em>
X( 3,7) → X¹ ( -3,-7)
Y(6,7) → Y¹ (-6,-7)
Z(4,2) → Z¹( -4 ,-2)
Divide the stack into halves, if the stacks are equal, they are even. If they aren't, they are odd.
Answer: The answer be 87 for both answer's
Step-by-step explanation:
because, {B-3=90} and, 0.< a < 90. and I calculated and got 87 for both questions ( I hope it correct!)
X = -1, so the statement is false
Answer:
20
Step-by-step explanation:
Given: F = 11, C = 11, E=?
By Euler's formula, we have:

Hence, the solid will have 20 edges.
