It has 1 set of 3 parallel lines and 3 sets of 2 parallel lines, and 18 angles (3 sides meet at each vertex)
18
It has 12 right angles. 4 on each rectangular side. 3*4 = 12
Three pairs and one triplet. The triplet can be considered three pairs.
bcoz in triangular prism, sides are not parallel so rays will deflect but in rectangular prism sides are parallel so rays won't deflect instead they will pass straight.
5 pairs of parallel lines, plus a set of 5 parallels.
A triangular prism has 9 parallel lines
A rectangular prism has 3 sets of 4 parallel lines and 24 angles.
A triangular prism can have right angles. If the prism has two triangular ends, then each of the three 'sides' meets each of the ends at right angles.
In a general triangilar prism, none.In a right triangular prism, three pairs and one triplet.In a general triangular prism, none. In a right triangular prism, three pairs and one triplet.
The parallel bases would be the two triangular faces, on either end of the prism.
None - each of the faces (including the bas) is a triangle - triangles do not have any parallel lines.
Yes, every prism has 2 parallel bases.
Yes.
there is none
