Question

Which of the following statements is true concerning ABC below?

A. B is the largest angle.
B. B is the smallest angle
C. A is the largest angle
D. A is the smallest angle

Answer 1

D. A is the smallest angle

Explanation:

Angle A's lines are closest together

Answer 2

D. A is the smallest angle

Explanation:

To answer this question properly, we need to remember that the sum of the three angles, in a triangle, must result in 180º. Besides, each leg of this triangle is in the opposite direction to the angle of its vertex.

Finally, with the help of a compass we can demonstrate it even better, but in short, the larger the leg the larger the angle. So, ∠A is the smallest angle since a measures 7 units, then comes ∠B for b measures 10 units and ∠C as the largest angle for c measures 12 units.
