Question

as part of a group exercise, four students each randomly selected 3 cards with angle measures written on them. The table shows the results.

Answer 1

Option (A)

Explanation:

As we know sum of interior angles of a triangle = 180°

If the sum of angles written on 3 cards is equal to 180°, will make a triangle.

Total of Alisha's cards = 100° + 90° + 170°

= 360°

Total of Aella's cards = 60° + 25° + 95°

= 180°

Total of Andrew's cards = 35° + 35° + 35°

= 105°

Total of Ah Lam's cards = 90° + 60° + 35°

= 185°

Since total of Aella's cards is 180°, triangle is possible with the angles given on the cards of Aella only.

Therefore, Option (A) will be the answer.
