To find the endpoints and lengths of the perpendicular bisectors of the triangle, we need to follow these steps:
 Find the midpoints of each side of the triangle.
 Determine the slopes of the sides of the triangle.
 Find the negative reciprocal of each slope to obtain the slopes of the perpendicular bisectors.
 Use the midpoint and the slope to find the equation of each perpendicular bisector.
 Solve for the endpoints of each perpendicular bisector.
Let's go through these steps:

Midpoints of each side:
 Midpoint of (5, 4) and (7, 9): ((6, 6.5))
 Midpoint of (7, 9) and (5, 8): ((6, 8.5))
 Midpoint of (5, 4) and (5, 8): ((5, 6))

Slopes of each side:
 Slope of (5, 4) to (7, 9): (m_1 = \frac{9  4}{7  5} = \frac{5}{2})
 Slope of (7, 9) to (5, 8): (m_2 = \frac{8  9}{5  7} = \frac{1}{2})
 Slope of (5, 4) to (5, 8): (m_3) is undefined (vertical line)

Negative reciprocal of slopes:
 Negative reciprocal of (m_1): (m_{\text{perpendicular 1}} = \frac{1}{m_1} = \frac{2}{5})
 Negative reciprocal of (m_2): (m_{\text{perpendicular 2}} = \frac{1}{m_2} = 2)

Equation of perpendicular bisectors:
 For side 1: (y  6.5 = \frac{2}{5}(x  6))
 For side 2: (y  8.5 = 2(x  6))
 For side 3: (x = 5) (vertical line)

Endpoints of perpendicular bisectors:
 For side 1: Solve the equation with known points (6, 6.5) and (5, 4), yielding the endpoint.
 For side 2: Solve the equation with known points (6, 8.5) and (7, 9), yielding the endpoint.
 For side 3: The equation is already a vertical line, so the endpoint can be determined from the given points.
The lengths of these perpendicular bisectors can then be calculated using the distance formula between the endpoints.

When evaluating a onesided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
