Example 2 Continued The x-coordinates are 8, 6 and Holt McDougal Geometry Medians and Altitudes of Triangles An altitude of a triangle is a perpendicular segment from a vertex to the line containing the opposite side. Substitute 1 for y. Subtract from both sides. Notice that the lines containing the altitudes are concurrent at P.

Notice that the lines containing the altitudes are concurrent at P. Triangle Congruence Section A Quiz. Feedback Privacy Policy Feedback. Add 6 to both sides. Every triangle has three altitudes. The centroid is always inside the triangle.

Find the coordinates of each point. Substitute 7 for ZW.

Substitute 6 for y1, and 3 for x1. Altitude—A segment from a vertex to the. RN is a horizontal line.

Vocabulary Median—A segment with endpoints being a vertex of a triangle and the midpoint of the opposite side. Every triangle has three altitudes. This point of concurrency is the orthocenter of the triangle.

This line must pass through Y 3, 6.

Substitute 1 for y. Find the midpoint of. About project SlidePlayer Terms of Service. Step 1 Graph the triangle. An altitude can be inside, outside, or on the triangle.

Multiply both sides by 3.

## 8.3 medians and altitudes of triangles answers

Make a conjecture about the centroid of a triangle. Write an equation of the line containing the points 3, 1 and 2, 10 in point-slope form. Since XY is vertical, the altitude is horizontal. The slope of a line perpendicular to XZ is. The y-coordinates are 6, 2 and 7. The coordinates of the centroid are D 3, 4.
