Question

25. Define
(a) collinear point
(b) straight line
(c) Ray
(d) line segment​

Answer 1

Answer:

a) In geometry, two or more points are said to be collinear, if they lie on the same  Non-Collinear Points

b) A line that does not curve. In geometry a line is always straight (no curves).

c) A ray is a vector from a point to a point . In geometry, a ray is usually taken as a half-infinite line (also known as a half-line) with one of the two points and. taken to be at infinity.

d) A line segment is a straight line that passes through the two points.

Hey Mate here is your ans plz mark me the brainliest : )

Answer 2

Answer:

a) Points which are at equal distance from each others are called collinear point.

b) A group of points forming an angle of 360° is called a line.

c) A ray is set of line which can be produced infinitely from one point only.

d) A part of line which has two end points and can not exceed furthur.

MORE TO KNOW -

• Perpendicular lines - when two lines intersects at right angles then they are said to be perpendicular lines.

• Angles - formed by two rays and common vertecs.

• parallel lines - Lines which do not have a common point and do not meet are called parallel lines.

• Intersecting lines - Lines which meets at a point are called intersecting lines.
