Regular-Area of Parallelograms, Triangles, and Trapezoids

Front

What is a parallelogram?

Back

A parallelogram is a four-sided figure (quadrilateral) where opposite sides are parallel and equal in length.

Front

How do you calculate the area of a parallelogram?

Back

The area of a parallelogram is calculated using the formula: Area = base × height.

Front

What is a triangle?

Back

A triangle is a three-sided polygon with three angles.

Front

How do you calculate the area of a triangle?

Back

The area of a triangle is calculated using the formula: Area = (base × height) / 2.

Front

What is a trapezoid?

Back

A trapezoid is a four-sided figure (quadrilateral) with at least one pair of parallel sides.

Front

How do you calculate the area of a trapezoid?

Back

The area of a trapezoid is calculated using the formula: Area = (1/2) × (base1 + base2) × height.

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 are the properties of a rectangle?

Back

A rectangle has four right angles, opposite sides that are equal, and diagonals that bisect each other.

Front

What is the significance of vertices in geometry?

Back

Vertices are the points where two or more lines meet, forming angles in shapes.

Front

How do you find the fourth vertex of a rectangle given three vertices?

Back

To find the fourth vertex, use the properties of rectangles: the x-coordinates and y-coordinates of opposite vertices are equal.
