☆☆☆☆☆Coplanar lines that do not intersect are called parallel lines.
It would be an obtuse triangle with one angle being greater than 90 degrees.
Yep. All equilateral triangles are isosceles triangles.
I got the answer:
if first#=A, second#=B, third#=C, fourth#=D, fifth#=E
The fifth number plus the third number equals fourteen. E+C=14
The fourth number is one more than the second number. D=B+1
The first number is one less than twice the second number. A=(B*2)-1
The second number plus the third number equals ten. B+C=10
The sum of all five numbers is 30. A+B+C+D+E+F=30
Observing, B is present in most clues.
Then use last clue A+B+C+D+E=30
Since E+C=14 just take out E and C then put 14
A+B+D+14=30
A+B+D=30-14
A+B+D=16
Substitute remaining clues
[(B*2)-1] + B + (B+1) = 16
(B*2) -1 + B + B + 1 = 16 -> negative one plus one is zero
(B*2) + 2B = 16
(B*2) = 16 - 2B
B*2 = 2 (8-B)
B*2 = 2 (8-B) -> divide both sides by 2
B = 8 - B
B + B = 8
2B = 8 -> divide both sides by 2 (sorry i know theres a short cut to this hehehe)
B = 4
Apply to clue #2:
D = B+1
D = 4+1
D = 5
then
A + B + C + D + E = 30, where B= 4, D= 5, E+C=14
A + 4 + 14 + 5 = 30
A = 30 - 4 - 14 - 5
A = 7
Using clue # 4
B + C = 10
4 + C = 10
C = 10 - 4
C = 6
Using clue #1
E + C = 14
E + 6 = 14
E = 14 - 6
E = 8
The Answer is 7, 4, 6, 5, 8
Thats it!!!
False
an interior angle + and exterior = 180 Angle A: 180-30=150 Angle B: 180-60=120 Angle C: 180-90=90 Angle D: 180-120=60 SO WHATS THE ANSWER!!!?????
An isosceles triangle must have two sides of equal size.
Since you have a side of 7 and 5, for it to be isosceles, your third side must be either 7 or 5.
7cm
No. An isosceles triangle has, by definition, two sides of equal length. A scalene triangle has, by definition, no sides of equal length. So, by definition (and the fact that 0 is not 2), an isosceles triangle cannot be scalene.

Greater than zero and less than eleven.
The sum of the lengths of any two sides of a triangle is greater than the length of the third side.
Congruent - SSS
A triangle with two congruent sides is an isosceles triangle, and a triangle with three congruent sides is an equilateral triangle.
A triangle can be Acute, Obtuse, or Right, depending on the angle. It can be Scalene, Isosceles, or Equilateral, depending on the length of the sides.
No, it is not.

No, it could not. A triangle cannot have a perimeter of length zero.
