List at least three shapes, other than hexagons, In the table. If the shape is a polygon, indicate whether the shape is regular or irregular. Find the number of lines of reflection that will map each shape back on to itself when the shape flips about the line. Also describe the position of the line of reflection.

ShapeNumber of Lines of ReflectionDescription

equilateral triangle33 perpendicular bisectors of the sides

regular heptagon77 perpendicular bisectors of the sides

regular octagon84 perpendicular bisectors and 4 lines joining pairs of opposite vertices

Step-by-step explanation:

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

i believe that the slope of the line is -5
