The slopes of perpendicular lines are opposite reciprocals.
true
false

true

Step-by-step explanation:

The slopes of prependicular lines have to give as a result -1 when multiplied by eachother, so for example if you have a line with a slope of 2, the perpendicular line should have a slope of -1/2 because when multiplying for one another the result will be -1. So the statement would be true, the slopes of perpendicular lines are opposite reciprocals.

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "
