☆☆☆☆☆Coplanar lines that do not intersect are called parallel lines.
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

D--C
It would be an obtuse triangle with one angle being greater than 90 degrees.
Yep. All equilateral triangles are isosceles triangles.
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
The third side must be longer than 11 and shorter than 19.
A triangle, but only if the line segments are straight.
not all congruent angles are vertical angles. Vertical angles must share a vertex.
Answer is a skew lines do not lie in the same place
vertical and supplementary
The length of the third side of an equilateral triangle is
the same as the lengths of both of the other two sides.
3 vertices in a triangle, whether it is equilateral, isosceles or scalene; acute angled, right or obtuse.
A triangle with two congruent sides is an isosceles triangle, and a triangle with three congruent sides is an equilateral triangle.
Perpendicular lines intersect at a 90 degree angle. Parallel lines do not intersect, nor would they ever intersect if continued infinitely.
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 could not. A triangle cannot have a perimeter of length zero.
