Q. Can the sides of a triangle have lengths 4, 8, and 10?Choices:(A) yes(B) no
Triangle Inequality Theorem: To determine if these can be the sides of a triangle, we need to check the triangle inequality theorem. The sum of the lengths of any two sides must be greater than the length of the third side.
Check 4+8>10: Check if 4+8>10. Calculation: 4+8=12, and 12>10, so this part is true.
Check 4+10>8: Check if 4+10>8. Calculation: 4+10=14, and 14>8, so this part is true too.
Check 8+10>4: Check if 8+10>4. Calculation: 8+10=18, and 18>4, so this part is also true.
