Back

m<GEH = 27.5

Front

Find the length of BC.

Back

Length of BC = 9

Front

Front

Find the range of possible measures for the third side of a triangle with two sides measuring 12 and 7.

Back

5<x<19

Front

Definition of a centroid in a triangle.

Back

The centroid is the point where the three medians of the triangle intersect, and it divides each median into a ratio of 2:1.

Front

What is the Triangle Inequality Theorem?

Back

The sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Front

How to find the measure of an angle in a triangle given two angles?

Back

Use the fact that the sum of the angles in a triangle is 180 degrees.

Front

What is the formula for the length of a median in a triangle?

Back

Median length = 1/2 * sqrt(2a^2 + 2b^2 - c^2), where a and b are the lengths of the sides adjacent to the median and c is the length of the opposite side.

Front

What is the relationship between the angles and sides of a triangle?

Back

In a triangle, larger angles are opposite longer sides.
