How do I know if lines are perpendicular

2 answers:

8 0

You can tell if lines are perpendicular or not by seeing if meet in a right angle. A right angle is like a square, and the lines would have to be 90 degrees.

One example is when the two lines (horizontal and vertical) meet each other at the ends.

(You MUST make sure that they are directly horizontal and vertical. If not, they will either be acute or obtuse).

I hope this helped!

The answer is Internal Validity.

Internal Validity is high in an experiment. when it demonstrates persuasively that changes in behavior are caused by the independent variable and not by unknown factors.

What is Internal Validity?

Internal validity is defined as the degree to which the observed results represent the truth in the population under investigation and are not the consequence of methodological flaws.
Internal validity is the degree of certainty that the causal link being examined is reliable and unaffected by other factors or variables.
The extent to which study results may be extended (generalized) to other contexts, groups, or events is referred to as external validity.
