Question

give a definition for each of following terms. Are there other terms that need to be defined first? What are they, and how might you defined them? 1- parallel lines 2- perpendicular lines 3- line segment 4- radius of circle 5- square

Answer 1

parallel lines : 2 lines which never meet but they are same
perpendicular lines: a line is perpendicular to another if it meet or crosses right angle
radius of circle: a line from centre of a point on the circle
square: a 4 sided flat shape with straight lines where :- 1) all sides have equal length
2) every interior angle is a right angle

Answer 2

Correct 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 lines

2)perpendicular lines

3)line segment

4)radius of a circle

5)square

Yes there are other terms which need to be defined first, they are before defining the above definition.

• $\leadsto$$\tt{\pink{\boxed{\boxed{Plane:}}}}$ Flat surfaces in which geometric figures can be drawn are known are plane.
• A plane surface is a surface which lies evenly with the straight lines on itself.

• $\leadsto$$\tt{\pink{\boxed{\boxed{Line}}}}$: A collection of points that has only length and no breadth is known as a line. And it can be extended on both directions.
• A line is breadth-less length.

Now, lets move ahead .

$\leadsto$$\large\star\tt{\pink{\underline{Parallel\: lines}}}$- Parallel lines are those lines which never intersect each other and are always at a constant distance perpendicular to each other. Parallel lines can be two or more lines.

$\leadsto$ $\large\star\tt{\red{\underline{Perpendicular\: lines}}}$- Perpendicular lines are those lines which intersect each other in a plane at right angles then the lines are said to be perpendicular to each other.

$\leadsto$$\large\star\tt{\blue{\underline{Line\: Segment}}}$- When a line cannot be extended any further because of its two end points then the line is known as a line segment. A line segment has 2 end points.

$\leadsto$$\large\star\tt{\purple{\underline{Radius\: of \:circle}}}$- A radius of a circle is the line from any point on the circumference of the circle to the center of the circle.

$\leadsto$ $\large\star\tt{\green{\underline{Square}}}$- A quadrilateral in which all the four sides are said to be equal and each of its internal angle is right angles is called square.
