Olympiad Test: Geometrical Shapes - 1 - Question 3

Which of the following is an open-sided figure?

Detailed Solution: Question 3

An open-sided figure is one where the lines do not connect to form a complete shape. A line does not connect at both ends, making it an open figure.

Olympiad Test: Geometrical Shapes - 1 - Question 4

What is the sum of the interior angles of a triangle?

Detailed Solution: Question 4

The sum of the interior angles of a triangle is always 180 degrees, regardless of the type of triangle.

Olympiad Test: Geometrical Shapes - 1 - Question 5

Which of the following is not a polygon?
