What is the Triangle Inequality Theorem?

Back

The Triangle Inequality Theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Front

If two sides of a triangle are 6.5 ft and 9.2 ft, what is the greatest possible whole number measure for the third side?

Back

14 ft

Front

If two sides of a triangle are 3.1 ft and 4.6 ft, what is the least possible whole number measure for the third side?

Back

2 ft

Front

What are the conditions for three lengths to form a triangle?

Back

The lengths must satisfy the Triangle Inequality Theorem: a + b > c, a + c > b, and b + c > a.

Front

Given the side lengths 7, 10, and 5, will these form a triangle?

Back

Yes

Front

Is it possible to form a triangle with side lengths 1, 2, and 1?

Back

No

Front

What is the measure of angle TQR if the options are 43, 90, 47, and 8?

Back

43

Front

Define a scalene triangle.

Back

A scalene triangle is a triangle in which all three sides are of different lengths.

Front

Define an isosceles triangle.

Back

An isosceles triangle is a triangle that has at least two sides of equal length.

Front

Define an equilateral triangle.

Back

An equilateral triangle is a triangle in which all three sides are of equal length.
