a plane triangle is a normal triangle, like the isosceles, right angled, equilateral and scalene triangle.
A triangle is a plane figure so it has two dimensions: length and breadth.
yes it does
An edge is the set of points where two (or more) planes meet. Since a triangle must be in just one plane, it cannot have any edges. It has one face, which is part of the plane containing the triangle.
ones that can be drawn in the plane such as a triangle, circle, etc. A sphere is not one.
If you were to have 3 points on the same line, then you would actually not be determining a plane, because there are infinitely many planes that can intersect a given line. But if you have 3 points in the form of the points (or vertices) of a triangle, then you determine a plane in the sense that there is only one possible plane upon which that triangle can be drawn (not including a degenerate triangle, which is equivalent to a line).
The complement of the triangle in the plane.
A plane triangle looks like a common triangle. A plane triangle is solved with linear units. A spherical triangle is found inside of a sphere. This type of triangle is solved with angular units.
Triangle Plane Square
It is a triangle
No- a triangle is a plane figure, not a solid.
A triangle. The effect of turning will depend on whether the plane containing the triangle is rotated - that is, the triangle is rotated around an axis perpendicular to its plane. In that case, it will appear upside down. Alternatively, it can be rotated about an axis in the plane of the triangle. In this case it will appear flipped.
No, never in plane geometry.
Every point in the plane outside the triangle can fall there!
In Euclidean plane geometry every triangle MUST BE coplanar.
There are 180 degrees in every plane triangle.
