Front

What is a triangle?

Back

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry.

Front

What are the types of triangles based on their sides?

Back

The types of triangles based on their sides are: Equilateral (all sides equal), Isosceles (two sides equal), and Scalene (no sides equal).

Front

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

Back

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

Front

What is a quadrilateral?

Back

A quadrilateral is a polygon with four edges (sides) and four vertices (corners).

Front

What are the types of quadrilaterals?

Back

The types of quadrilaterals include squares, rectangles, rhombuses, parallelograms, trapezoids, and kites.

Front

What is the formula for the area of a rectangle?

Back

The area of a rectangle is calculated using the formula: Area = length × width.

Front

What is a circle?

Back

A circle is a shape consisting of all points in a plane that are at a given distance from a fixed point, called the center.

Front

What does the radius of a circle represent?

Back

The radius of a circle is the distance from the center of the circle to any point on its circumference.

Front

What is the formula for the circumference of a circle?

Back

The circumference of a circle is calculated using the formula: Circumference = 2πr, where r is the radius.

Front

What is the relationship between the diameter and radius of a circle?

Back

The diameter of a circle is twice the length of the radius. (Diameter = 2 × Radius)
