Question

give a definition for each of the following terms .are there other terms that need to be defined first ? what are they , and how might you define them? 1 parallel line

Answer 1

sorry but take a look at this

For unique solution a1/a2 should not be equal to b1/b2 ...so 4/k =1/1

if we cross multiply them we get k is equal to 4...

Bt as the question says it is a unique solution so we'll write it as k should bt be equal to 4

hope it helps you

Answer 2

Answer:

Parallel Lines:

Two lines are said to be parallel to each other if they never meet (intersect) with each other.

• The distance between the lines always remains the same.

• Parallel lines help in understanding the relationship between paths of object and sides of shapes (example: rectangle has opposite sides parallel and equal, a parallelogram has opposite sides parallel)

• Examples: Zebra crossing on the road, Rail tracks, etc.

• Lines AB and CD are parallel on a plane surface.

• Denoted by pair of vertical lines ( ) ;.

Answer: A set of two or more lines that never intersect and are always the same distance apart from each other are called parallel lines.

More information:

For defining these terms, we should have knowledge about the following:

1. Point: A point is an exact position on a plane surface. It is usually denoted by a capital single letter (say 'X').
2. Line: A line is the shortest distance between two points.
3. Surface: A portion of space having length and breadth but no thickness.
4. Angle: An angle is defined as a figure that is formed at the place where two lines meet. It is measured in degree or radian.
