Below are sample questions representative of the exercises included on this worksheet and related GEO.81 Use triangle special segments to solve problems skill assessments:

Problem 1Difficulty: Mastery
Triangle ABC has A(0, 0), B(12, 0), and C(0, 6). A student says the centroid is the midpoint of the hypotenuse, (6, 3). What is the correct response?
AThe centroid is (4, 2); (6, 3) is the circumcenter.
BThe centroid is (6, 3); the student is correct.
CThe centroid is (0, 0); the right-angle vertex is always the centroid.
DThe centroid is (12, 6); add the legs to find it.
Solution & Explanation:The centroid averages all three vertices: ((0 + 12 + 0)/3, (0 + 0 + 6)/3) = (4, 2). The midpoint of the hypotenuse of a right triangle is the circumcenter, not the centroid.
Problem 2Difficulty: Mastery
In triangle ABC, AD meets BC at D, BD = DC, and AD is perpendicular to BC. Which conclusion is justified?
AAD is a median, an altitude, and the perpendicular bisector of BC.
BAD is a midsegment parallel to BC.
CAD cannot be an angle-related segment.
DAD is the circumcenter of the triangle.
Solution & Explanation:BD = DC makes D the midpoint of BC, so AD is a median. Since AD is perpendicular to BC at its midpoint, it is also an altitude and the perpendicular bisector of BC.
Problem 3Difficulty: Mastery
Vertex A is (1, 13), and M(10, 1) is the midpoint of the opposite side. Point G is the centroid on median AM. What is G?
A(4, 9)
B(6, 7)
C(7, 5)
D(10, 1)
Solution & Explanation:The centroid is two thirds of the way from A to M. The change from A to M is (9, -12), and two thirds of that is (6, -8). Add to A to get (7, 5).
