A square has 4 lines of symmetry.
- True
- False
Correct Answer

A. True

Explanation

A square has 4 lines of symmetry because it has 4 equal sides and 4 equal angles. When a square is folded along any of its lines of symmetry, each half will perfectly match the other half. Therefore, a square can be divided into 4 congruent parts using its lines of symmetry.

Raihana has $ 100. She buys 2 dolls and a backpack. How much change money would she get?
- $ 40
- $ 50
- $ 60
Correct Answer

A. $ 60

Explanation

Raihana has $100 and she buys 2 dolls and a backpack. The cost of the dolls and backpack is not mentioned in the question. However, since she is getting change money, it can be inferred that the cost of the dolls and backpack is less than $100. Therefore, the maximum amount of change she can get is $100 (her initial amount) minus the cost of the dolls and backpack. Since $60 is the only option that is less than $100, it is the correct answer.

An equilateral triangle has three lines of symmetry.
- True
- False
Correct Answer

A. True

Explanation

An equilateral triangle has three lines of symmetry because it can be divided into three equal parts by rotating it 120 degrees around each of its vertices. Each rotation creates a line of symmetry that divides the triangle into two congruent halves. Therefore, an equilateral triangle has three lines of symmetry.

This shape has no line of symmetry.
- True
- False
Correct Answer

A. True

Explanation

The statement says that the shape has no line of symmetry. In geometry, a line of symmetry is a line that divides a shape into two equal halves, such that if you fold the shape along the line, the two halves would perfectly overlap. Therefore, if the shape has no line of symmetry, it means that it cannot be folded in any way to create two equal halves. Hence, the correct answer is true.
