Give an example from your classroom of three collinear points
2 answers:
Collinear point are the point which lie on the same straight line.
Let us take an example of the sitting arrangements of students in a classroom.
The students sitting in a desk in a row are collinear. Let us suppose that 3 students sit in a desk in horizontal direction then these represent collinear points. Students 1, 2 and 3 are collinear points.
Similarly, , students 1, 4 and 5 in the column are collinear points.
Please see the attached image to understand this.

Answer:
The new points to the triangle will be:
Step-by-step explanation:
Because the reflection point is at , all x values will subtract their distances from
to get their new values. The y values remain the same.
The starting values are:
Point is 5 units away from
, so we'll subtract 5 from -1 to get the new x value:
, so
.
Point is also 5 unit away from
, so we'll subtract 5 from -1 to get the new x value:
, so
.
Point is 7 units away from
, so we'll subtract 7 from -1 to get the new x value:
, so
.
