+Answer 4.7 – 30
shortest: WX
longest: YW
+Question 4.7 - 40
Can the side lengths form a triangle? Explain.
+Answer 4.7 – 40
No, because 2 + 4 = 6.
Yes, because the sum of two sides is greater than the sum of the third in all three cases. A triangle can be formed.
No, because 5 + 11 < 17.
+Question 4.7 - 50
+Answer 4.7 – 50
Yes, because the sum of two sides is greater than the third side in all three cases. A triangle can be formed with these measurements.
