Four Sided Triangle is a 1953 British science-fiction film directed by Terence Fisher, adapted from the 1949 novel by William F. Temple. It stars Stephen Murray, Barbara Payton and James Hayter. It was produced by Hammer Film Productions at Bray Studios.
The first figure is four-sided. The second figure is an open shape. The third figure has a curved side. Parts of a Triangle. A triangle has 3 sides. In triangle ABC, the sides are AB, BC, and CA. The angle formed by any two sides of a triangle is the angle of the triangle, denoted by the symbol ∠. A triangle has three angles.
A quadrilateral is defined as a two-dimensional shape with four sides, four vertices, and four angles. There are two main types: concave and convex. There are also various subcategories of convex quadrilaterals, such as trapezoids, parallelograms, rectangles, rhombi, and squares.

- Yes, they have to be closed. In fact, all polygons have to be closed.
- The area formula for a Rhombus is: A = (1/2) (d1) (d2) d1 & d2 represent the length of the 2 diagonals
- the rhombus is a slanted square and the parallelogram is a slanted rectangle. they both are quadrilateral. The term 'quadrilateral' means 4 sides....
- A rectangle has 4 straight sides and 4 right angles. A rhombus must have opposite equal angles and 4 equal sides. A square has 2 sets of opposite r...
- Yes, all polygons are defined as closed figures.
- Even though you may think there is another parallel side for each side in a regular hexagon, the definition of a parallelogram is a four-sided plan...
- Yes. All squares are both rectangles and rhombi.
- not necessarily. the weird pink shape that he showed did not have equal sides
- So you start with a parallelogram, two pairs of parallel sides, opposite sides are congruent, adjacent angles are supplementary, diagonals bisect e...
