Coplanar lines that do not intersect are called

Coplanar lines that do not intersect are called parallel lines.

What is diagonal of quadrilateral

A quadrilateral is an object formed by four straight lines - two of which meet at an angle. A diagonal is one of the lines which go from one angle to the one other angle in the quadrilateral which it is not already connected to.

If the angles of the quadrilateral are A, B, C and D, and A is connected by a straight line to B and D then the diagonal is a line between A and C.

A--B

What is the measure of RVE

If the square of the length of the longest side of a triangle is greater than the sum of the squares of the lengths of the other two sides of what kind of triangle

It would be an obtuse triangle with one angle being greater than 90 degrees.

Are some isosceles triangles equilateral triangles

Yep. All equilateral triangles are isosceles triangles.

The fifth number plus the third number equals 14

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!!!

How many degrees are there in each exterior angle of an equilateral triangle A 30 degrees B 60 degrees C 90 degrees D 120 degrees

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!!!?????

The lengths of 2 sides of an isosceles triangle are 7 and 5 what are all the possible lengths of the third side

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.

What is the measure of RSL

144

3x2 plus 5x plus 10 equals 0

3x + 5x + 10 = 0
a = 3, b = 5, c = 10

D = b - 4ac = 25 - 120 = -95
Since D < 0, we have two conjugate complex roots.

√D = √-95 = i√95

x = (- b ± √D)/2a

x = -5/6 + [(√95)/6]i or x = -5/6 -[(√95)/6]i

8 three fourths feet is how many inches

8 3/4 ft. = 104 inches

12 inches in a foot

8 inches in 3/4 of a foot.

(8 x 12) + 8 = x

96 + 8 = x

x = 104

Which term best describes a figure formed by three segments connecting three noncollinear points

A triangle, but only if the line segments are straight.

What is the difference between vertical angles and congruent angles

not all congruent angles are vertical angles. Vertical angles must share a vertex.

What is a true statement about skew lines

Answer is a skew lines do not lie in the same place

Are RDY and NDA are vertical angles

vertical and supplementary

How many vertices in a scalene triangle

3 vertices in a triangle, whether it is equilateral, isosceles or scalene; acute angled, right or obtuse.

What is a triangle with at least two congurent sides

A triangle with two congruent sides is an isosceles triangle, and a triangle with three congruent sides is an equilateral triangle.

What is perpendicular an d parallel lines

Perpendicular lines intersect at a 90 degree angle. Parallel lines do not intersect, nor would they ever intersect if continued infinitely.

Is a triangle obtuse scalene or 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.
