Not too sure of the question but if A is (1, 2) and B is (-3, -1) then it is a right angle triangle if the coordinates of C are at (1, -1) or (-3, 2)

If you mean vertices of: (-1, -1) (-1, 3) and (5, -1) then when plotted on the Cartesian plane it will form a right angle triangle with a base of 6 units and a height of 4 units. Area of triangle: 0.5*6*4 = 12 square units

3 vertices, 3 edges and 1 face.

Faces: 1 Vertices: 3 Edges: 3

If the vertices are at (0, -2) (8, -2) and (9, 1) on the Cartesian plane plane then by using the distance formulae and trigonometry the area of the triangle works out as 12 square units.

The area is calculated easily using the determinant of the matrix of coordinates, or Heron's formula and is 15 square units.

Cube: 6 faces, 12 edges and 8 vertices. Cuboid: 6 faces, 12 edges and 8 vertices. Sphere: 1 Face and no edges or vertices. Cylinder: 3 faces, 2 edges and no vertices. Cone: 2 faces, and 1 edge and vertices. Triangle Pyramid: 4 faces and vertices and 6 edges. Square Pyramid: 5 faces and vertices and 8 edges. Triangle Prism: 5 faces, 9 edges and 6 vertices. Examples, Cube: A box Cuboid: A keyboard Sphere: A ball Cylinder: Can of beans Cone: Ice-cream cone Triangle Pyramid: Bit of a tobarone bar Square Pyramid: Egyptian Pyramid Triangle Prism: Tobarone Bar

There are only 5 known regular Platonic solids and they and their properties are:- 1 Tetrahedron: (pyramid) 4 equilateral triangle faces, 6 edges and 4 vertices 2 Hexahedron (cube) 6 square faces, 12 edges and 8 vertices 3 Octahedron: 8 equilateral triangle faces, 12 edges and 6 vertices 4 Dodecahedron: 12 regular pentagon faces, 30 edges and 20 vertices 5 Icosahedron: 20 equilateral triangle faces, 30 edges and 12 vertices All of them can be inscribed inside a sphere.

Just calculate the length of the three sides using the distance formula, then compare which is largest.

Triangular prism has 6 vertices. Square pyramid has 5 vertices. Answer: 1 vertex.

A triangle has 3 sides, 1 face and 3 vertices.

All you have to do is add the numbers and determine how much the numbers change. In your case, the new coordinates are (0, -1), (4, -2), (2, -6).
