a triangular prism easy
To indicate that a pair of lines are parallel you mark them both with an arrow. If there is another pair of parallel lines on the same shape you mark those with a double arrow.
I dont know the answer............................
The faces of a cube are all the same shape - a square.
NO!!!! Parallelogram : Two pairs of parallel lines ; The each pair of parallel lines is the same length. Trapezium ; One pair of parallel lines, that are not the same length. The other two sides can be the same length , but not parallel. Both figures/shapes are quadrilaterals.
Not exactly. They are two names for the same shape. The typical shape consists of a four-sides figure with opposite sides (and angles) equal. Each pair of parallel sides are the same length.
A regular tetrahedron (triangular pyramid).
3d shape Well actually it is a Cube
a triangular pyramid.
A parallelogram is a plane, or two-dimensional shape that is bounded by four straight lines which form its sides. Each pair of opposite sides consists of parallel and congruent (same length) lines.
