Explain how to determine if a triangle is acute, right, or obtuse based on its angles.
A triangle is always classified as equilateral.
The triangle is classified based on its side lengths only.
The triangle is classified as acute, right, or obtuse based on the measures of its angles.

How does the property of angles in a triangle help in solving for unknown angles?
The angles in a triangle can be any value, regardless of their sum.
The property of angles in a triangle states that the sum of the angles is 180 degrees, which helps in calculating unknown angles.
The angles in a triangle are always equal to each other, making calculations unnecessary.
The property of angles in a triangle states that the sum of the angles is 360 degrees.
If the angles of a triangle are in the ratio 2:3:4 and one angle is 48°, what are the measures of the other two angles?
40°, 80°
50°, 70°
30°, 60°
20°, 90°
What is the relationship between exterior angles and interior angles in a triangle?
The exterior angle is always greater than the largest interior angle.
The sum of all angles in a triangle is equal to the exterior angle.
Each interior angle is equal to the corresponding exterior angle.
The exterior angle of a triangle is equal to the sum of the two opposite interior angles.
