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

Can the side lengths 20.2 in., 11 in., and 8.2 in. form a triangle?

Back

No, these side lengths cannot create a triangle because 20.2 + 11 is not greater than 8.2.

Front

What is the smallest angle in a triangle?

Back

The smallest angle in a triangle is the angle opposite the shortest side.

Front

What is a scalene triangle?

Back

A scalene triangle is a triangle with all sides of different lengths.

Front

What is an isosceles triangle?

Back

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

Front

What is an equilateral triangle?

Back

An equilateral triangle is a triangle with all three sides of equal length.

Front

What is a right triangle?

Back

A right triangle is a triangle that has one angle measuring 90 degrees.

Front

What is the greatest common factor (GCF) of two numbers?

Back

The GCF of two numbers is the largest number that divides both of them without leaving a remainder.

Front

What is the GCF of 25 and 36?

Back

The GCF of 25 and 36 is 1.

Front
