a.
To classify: the triangle as acute, obtuse ,or right.
a.
Answer to Problem 3PS
Right triangle.
Explanation of Solution
Given information:The vertices of the triangle are given.
(a)(1,2,0),(0,0,0),(-2,1,0).
Formula Used:
Use distance formula for determine the triangle’s sides.
Where
Calculation:
The vertices of the triangle are given.
A(1,2,0),B(0,0,0),C(-2,1,0).
So, by using distance formula: the tringle sides.
Because
b.
To classify:the triangle as acute, obtuse, or right.
b.
Answer to Problem 3PS
Obtuse triangle.
Explanation of Solution
Given information:The vertices of the triangle are given.
(b)(-3.0,0),(0,0,0),(1,2,3).
Formula Used:
Use distance formula for determine the triangle’s sides.
Where
Calculation:
The vertices of the triangle are given.
A(-3,0,0),B(0,0,0),C(1,2,3).
So, by using distance formula: the tringle sides.
Because
c.
To classify: the triangle as acute, obtuse, or right.
c.
Answer to Problem 3PS
Obtuse triangle.
Explanation of Solution
Given information: The vertices of the triangle are given.
(c)(2,-3,4),(0,1,2),(-1,2,0).
Formula Used:
Use distance formula for determine the triangle’s sides.
Where
Calculation:
The vertices of the triangle are given.
A(2,-3,4),B(0,1,2),C(-1,2,0).
So, by using distance formula: the tringle sides.
Because
d.
To classify: the triangle as acute, obtuse, or right.
d.
Answer to Problem 3PS

Explanation of Solution
Given information: The vertices of the triangle are given.
(d)(2,-7,3),(-1,5,8),(4,6,-1).
Formula Used:
Use distance formula for determine the triangle’s sides.
Where
Calculation:
The vertices of the triangle are given.
A(2,-7,3),B(-1,5,8),C(4,6,-1).
So, by using distance formula: the tringle sides.
Because
