Card 3
Question: What is a point in basic geometric elements?
Answer: A location in space with no dimension.
Card 4
Question: How is a line defined in basic geometric elements?
Answer: A one-dimensional figure with no thickness, extending infinitely in two directions.
Card 5
Question: What is a plane?
Answer: A two-dimensional flat surface extending infinitely.
Card 6
Question: How is an angle formed and measured?
Answer: Formed by two rays sharing a common endpoint, called the vertex. Measured in degrees (°).
Card 7
Question: What is a triangle?
Answer: A polygon with three edges and three vertices. It is the simplest polygon and a fundamental building block in geometry.
Card 8
Question: How are triangles classified by side length?
Answer: Triangles are classified by side length into equilateral, isosceles, and scalene triangles.
Card 9
Question: What defines an equilateral triangle?
Answer: All three sides are equal in length, and all three angles are 60°.
Card 10
Question: What defines an isosceles triangle?
Answer: Two sides are equal in length, and the angles opposite these sides are equal.
