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.
