Difference of plane and spherical triangles?
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.
What is a plane figure with three sides?
It is a triangle
Is a triangle a solid figure?
No- a triangle is a plane figure, not a solid.
Can a triangle be coplanar?
In Euclidean plane geometry every triangle MUST BE coplanar.
How many degrees in an external triangle?
There are 180 degrees in every plane triangle.
What is the cross section formed by a plane that contains a vertical line of symetry for a tetrahedron?
It is a triangle.
What is a plane triangle?
a plane triangle is a normal triangle, like the isosceles, right angled, equilateral and scalene triangle.
Is the set of points that lie on the plane of the triangle but does not include the points on the triangle?
The complement of the triangle in the plane.
Difference of plane and spherical triangles?
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.
What geometric objects occupies two dimensions?
Triangle Plane Square
What is a plane figure with three sides?
It is a triangle
Is a triangle a plane shape?
No.
Is a triangle a solid figure?

Which formula can be derived by using the Pythagorean theorem in the coordinate plane?
The Pythagorean theorem, which is the square root of the sum of the squares of two sides of a right triangle is equal to the hypotenuse, can be used to find the distance between two points. This means that it can also be used to find the equation of a line.
What does a triangle turned 180 degrees look like?
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.
Is an equilateral triangle always a right triangle?
No, never in plane geometry.
What can fall outside a triangle?
Every point in the plane outside the triangle can fall there!
