HGeom - Chapter 5 Test

Front

What is a median in a triangle?

Back

A median is a line segment that connects a vertex of a triangle to the midpoint of the opposite side.

Front

What is an altitude in a triangle?

Back

An altitude is a perpendicular segment from a vertex to the line containing the opposite side.

Front

How do you determine the order of side lengths in a triangle?

Back

List the side lengths from shortest to longest based on their numerical values.

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

What does it mean for two triangles to be congruent?

Back

Two triangles are congruent if they have the same size and shape, meaning all corresponding sides and angles are equal.

Front

What is an indirect proof?

Back

An indirect proof assumes that the statement to be proven is false, leading to a contradiction.

Front

What is the significance of the side lengths 2 and 6 in triangle formation?

Back

To form a triangle with sides of lengths 2 and 6, the third side must be less than 8 and greater than 4.

Front

How do you find the value of x in a triangle problem?

Back

Use algebraic equations based on the properties of triangles, such as the sum of angles or side lengths.

Front

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

Back

In a triangle, larger angles are opposite longer sides, and smaller angles are opposite shorter sides.

Front

What is the definition of a triangle?

Back

A triangle is a polygon with three edges and three vertices.
