part 1:
Which set of angle measures could be the interior angles of a triangle?
A.
15°, 25°, 50°
B.
23°, 67°, 90°
C.
25°, 58°, 102°
D.
38°, 42°, 80°
part 2:
Which set of side lengths could be the sides of a triangle?
A.
1 cm, 2 cm, 3 cm
B.
5 cm, 9 cm, 18 cm
C.
7 cm, 16 cm, 24 cm
D.
10 cm, 24 cm, 26 cm

Respuesta :

Based on the triangle sum theorem and the triangle inequality theorem:

1. B. 23°, 67°, 90°.

2. A. 1 cm, 2 cm, 3 cm.

What is the Triangle Sum Theorem?

According to the triangle sum theorem, all three interior angles of any triangle has a sum of 180 degrees.

What is the Triangle Inequality Theorem?

Based on the triangle inequality theorem, one side of a triangle must be less than or equals the sum of any other two sides of the triangle. (a + b ≥ c).

Part 1:

23° + 67° + 90° = 180°, therefore, based on the triangle sum theorem, the set of angle measures that could be the interior angles of a triangle is: B. 23°, 67°, 90°.

Part 2:

1 + 2 = 3

1 + 3 > 2

2 + 3 > 1

Therefore, based on the triangle inequality theorem, the set of side lengths that could be that of the sides of a triangle is: A. 1 cm, 2 cm, 3 cm.
