What is a Equilateral equiangular? What is a quadrilateral? What is a quadrangle, a rhombus and a parallelogram? Quadrilateral has vertices A = (-2, 12), B = (-1, -1), C = (10, -8) and D = (9, 5). What is the quadrilateral?
Equilateral means that all the sides are the same size. Therefore an equilateral prism is has all sides the same length. This also means that they have 3 equal 60 degree angles. The definition of prism is a solid figure whose bases or ends have the same

A regular polygon has sides that have the same length and angles that have equal measures. Learn about what a polygon is and understand how to determine if a polygon is a regular polygon or not. What Is a Polygon? Before we talk about regular polygons, we need to talk about polygons!
congruent to triangle DEF, and they are not equilateral triangles, then the statement, "ABC is congruent to FED" is incorrect– that would be saying that line AB is equal to line FE, when in fact line AB is equal to line DE. The correct statement must be: "ABC is congruent to DEF"...
In the field of geometry, a quadrilateral is a closed geometric shape consisting of four points, such that any three points among them are non-collinear. A quadrilateral possesses four sides, four angles, and four vertices, making it a fundamental object of study in geometry....
