Triangles you use : (base x perpendicular height) divided by 2.
Parallelogram: you need to find the area of one of the side triangles, then double it (because there's two of them). Then find the area of the square in the middle, and add this to the area of the two triangles.
No, they are triangles.
parallelograms
They are both polygons
There are a total of three parallelograms in a triangular prism. Each of the sides are parallelograms, while the ends are triangles.
yes
A triangular prism.
Parallelograms of any form, a square, a rectangle, and a rhombus are just special parallelograms so all will form 2 pairs of isosceles triangles when a diagonal is drawn.
only for triangles and parallelograms as far as i know
Some shapes that fit that condition are parallelograms, scalene triangles, and trapezoids.
Triangular prism
Triangular prism
They are polygons. They have fewer than 5 sides. They have fewer than 5 vertices.
