Trapezoids

Front

What is a trapezoid?

Back

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

Front

What are the properties of an isosceles trapezoid?

Back

In an isosceles trapezoid, the legs are congruent, the base angles are congruent, and the diagonals are also congruent.

Front

How do you find the value of x in trapezoid problems?

Back

To find the value of x, set up equations based on the properties of the trapezoid and solve for x.

Front

What are the base angles of an isosceles trapezoid?

Back

The base angles of an isosceles trapezoid are the angles adjacent to each base, and they are congruent.

Front

What is the formula for the area of a trapezoid?

Back

The area of a trapezoid can be calculated using the formula: Area = (1/2) * (Base1 + Base2) * Height.

Front

What is the relationship between the angles in a trapezoid?

Back

In a trapezoid, the sum of the interior angles is always 360 degrees.

Front

How do you determine if a trapezoid is isosceles?

Back

A trapezoid is isosceles if its non-parallel sides (legs) are congruent.

Front

What is the significance of congruent angles in trapezoids?

Back

Congruent angles in trapezoids help in establishing relationships between sides and can be used to solve for unknowns.

Front

How do you find the length of the bases in a trapezoid?

Back

The lengths of the bases can be found using the properties of the trapezoid and any given dimensions or equations.

Front

What is the definition of congruent segments?

Back

Congruent segments are segments that have the same length.
