1. An isosceles triangle has vertices at A(8, -1),
B(4, 2), C(7, 6). Sides AB and BC are congruent.
You want to determine if the triangle is an
isosceles right triangle.
Write the numerical answers for the questions
below in fractional form.
4.
You can test whether a quadrilateral is a square
without measuring any of its side lengths. If
a quadrilateral has four right angles and its
diagonals are perpendicular, then it must be a
square.
What is the slope of AB?
Ouadrilateral MNPQ contains four right angles.
The vertices of quadrilateral MNPQ he at
M(-2, 4), N(4, 7), P(7, 1), and Q(1, -2).
What is the slope of BC?
Are sides AB and BC perpendicular?
Prove or disprove that the quadrilateral is also
a square by determining if the diagonals are
perpendicular.
Is the triangle an isosceles right triangle?
Simplify fractional answers as necessary:
What is the slope of MP?
2.
A circle is graphed on a coordinate system. The
center is at the origin, and the point (0, 3) lies on
the circle.
What is the slope of NQ?
Are diagonals MP and Q perpendicular?
You want to prove or disprove that the point
(1, v8) lies on the circle.
Is the quadrilateral a square?
What is the radius of the circle?
5. Which of the following sets of four coordinates
could not be the four vertices of a square?
What is the distance from the center to (1, "8)?
A. (-1, 0), (-1, 2), (-3, 0), (-3, 2)
Does the point (1, v8) lie on the circle?
B. (1, -3), (3, -3), (1, -5), (3, -5)
C. (1, 0), (4, 3), (4, -3), (7, 0)
D. (0, -2), (0, -4), (-3, -2), (-3, -s
