What is the definition of a triangle?

A triangle is a closed, two-dimensional shape with three straight sides and three angles that sum up to 180 degrees.

How many sides does a quadrilateral have?

A quadrilateral has 4 sides.

What is the difference between an equilateral triangle and an isosceles triangle?

An equilateral triangle is a triangle with all three sides of equal length, while an isosceles triangle is a triangle with at least two sides of equal length. In an equilateral triangle, all angles are equal (60 degrees), whereas in an isosceles triangle, only the angles opposite the equal sides are equal.

How are right triangles different from other types of triangles?

A right triangle is a type of triangle that contains a right angle, which measures 90 degrees. This distinguishes it from other types of triangles, such as equilateral, isosceles, or scalene triangles, which do not have a right angle. The presence of a right angle in a right triangle allows for special geometric properties and relationships to exist between its sides and angles, such as the Pythagorean theorem, which relates the lengths of the sides of a right triangle.

What is the formula for finding the area of a triangle?

The formula for finding the area of a triangle is 1/2 multiplied by the base of the triangle multiplied by the height of the triangle.

What are the properties of a parallelogram?

A parallelogram is a quadrilateral with opposite sides that are parallel and equal in length. It also has opposite angles that are equal in measure. The consecutive angles of a parallelogram add up to 180 degrees, and the diagonals bisect each other at their point of intersection. Additionally, the sum of the interior angles in a parallelogram is always 360 degrees.

What is the definition of a trapezoid?

A trapezoid is a quadrilateral with at least one pair of parallel sides. It is a geometric shape with four sides where the parallel sides are of unequal length, while the non-parallel sides may or may not be equal in length.

How many right angles does a rectangle have?

A rectangle has four right angles.

What is the difference between a square and a rhombus?

A square is a type of rhombus that has all sides equal in length and all angles equal to 90 degrees, while a rhombus is a quadrilateral with all sides of equal length but angles are not necessarily equal to 90 degrees. Therefore, all squares are rhombuses, but not all rhombuses are squares.

Can a quadrilateral have all sides of different lengths?

Yes, a quadrilateral can have all sides of different lengths. In fact, there are many different types of quadrilaterals such as a kite or a non-regular quadrilateral that can have all sides of distinct lengths.
