Triangle SRA is shown below. Use this to answer each of the following questions. Express answers in simplest form, including simplifying radicals if necessary. Use sqrt() for radical answers.
For example: if your answer is
you would enter: 3sqrt(5)

AR =
RS =
Which describe triangle is SRA? check all that apply.
What are the coordinates of the midpoint of line segment SA?
To input coordinates, use parentheses. For example type (-2,5) and not -2, 5. If your answers are not integers, used decimals rather than fractions.
What are the coordinates of the midpoint of line segment RA?
To input coordinates, use parentheses. For example type (-2,5) and not -2, 5. If your answers are not integers, used decimals rather than fractions.
