Question

match the following triangles with their correct definition.

acute triangle

all sides are the same length.

scalene triangle

has at least 2 equal sides.

isosceles triangle

has no equal sides.

equilateral triangle

has one right angle

right triangle

has 3 acute angles

Explanation:

Step1: Recall Triangle Definitions

• Acute Triangle: All angles are acute (less than \(90^\circ\)), so matches "Has 3 acute angles".
• Scalene Triangle: No equal sides, so matches "Has no equal sides".
• Isosceles Triangle: At least 2 equal sides, so matches "Has at least 2 equal sides".
• Equilateral Triangle: All sides equal, so matches "all sides are the same length".
• Right Triangle: Has one right angle (\(90^\circ\)), so matches "Has one right angle".

Step2: Match Each Triangle

1. Acute Triangle → Has 3 acute angles.
2. Scalene Triangle → Has no equal sides.
3. Isosceles Triangle → Has at least 2 equal sides.
4. Equilateral Triangle → All sides are the same length.
5. Right Triangle → Has one right angle.

Answer:

• Acute Triangle: Has 3 acute angles
• Scalene Triangle: Has no equal sides
• Isosceles Triangle: Has at least 2 equal sides
• Equilateral Triangle: All sides are the same length
• Right Triangle: Has one right angle
