Triangle Inequality Theorem Worksheets
Triangle Inequality Theorem worksheets help students practice a key concept in geometry. These worksheets focus on the rule that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. By solving problems on these worksheets, students learn how to test if three given lengths can form a triangle. This builds strong logic and problem-solving skills.
Teachers use these worksheets to guide students through simple and clear steps. First, students add two side lengths. Then, they compare the result with the third side. If the sum is greater, the sides can form a triangle. If not, they cannot. For example, with side lengths 3 cm, 4 cm, and 8 cm, students add 3 + 4 = 7, which is not greater than 8. So, these lengths cannot make a triangle.
A triangle with sides of length a, b, and c, it must satisfy that a + b > c, a + c > b, and b + c > a.
Moreover, these worksheets include a mix of question types. Some ask students to check if three sides form a triangle. Others provide missing values and ask for a possible range for the third side. These variations challenge students and keep them engaged. Some worksheets also include visual aids like triangles and number lines, which help visual learners.
