Question

Which type of triangle will always have exactly 1-fold reflectional symmetry? right triangle obtuse triangle equilateral triangle isosceles triangle

Answer 1

isosceles triangle ig

Answer 2

Isosceles Triangle

Explanation:

• Reflection symmetry exists when the figure can be folded over onto itself along a line. This line is called the line of symmetry.
• In a regular polygon, the number of lines of symmetry is equal to the number of sides in the polygon.
• Isosceles triangle is a type of triangle that will always have exactly 1-fold reflection symmetry.
• 1-fold reflection symmetry means that one line or 1 division can divide the whole figure into two symmetrical parts.

• An isosceles triangle is a triangle that has two sides of equal length. Isosceles triangle has at least one line of symmetry.

Thus, the answer is Option c) Isosceles triangle.
