Unit 4 Flashcardizz Quiz. Properties of Quadrilaterals

Front

What is a rhombus?

Back

A rhombus is a type of quadrilateral where all four sides are of equal length and opposite angles are equal.

Front

What is the property of angles in a rhombus?

Back

The opposite angles in a rhombus are equal, and the adjacent angles are supplementary (add up to 180 degrees).

Front

What defines a trapezoid?

Back

A trapezoid is a quadrilateral that has exactly one pair of parallel sides.

Front

What is an isosceles trapezoid?

Back

An isosceles trapezoid is a trapezoid in which the non-parallel sides are equal in length and the base angles are equal.

Front

How do you find the measure of an angle in an isosceles trapezoid?

Back

In an isosceles trapezoid, the base angles are equal, and the sum of the angles in any quadrilateral is 360 degrees.

Front

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

Back

The sum of the interior angles of a quadrilateral is 360 degrees.

Front

If two angles of a rhombus are 75 degrees, what are the measures of the other two angles?

Back

The other two angles would each measure 105 degrees, since opposite angles are equal and adjacent angles are supplementary.

Front

What is the relationship between the diagonals of a rhombus?

Back

The diagonals of a rhombus bisect each other at right angles and also bisect the angles of the rhombus.

Front

How do you solve for x in a rhombus when given angle measures?

Back

Use the properties of angles in a rhombus, knowing that opposite angles are equal and adjacent angles are supplementary.

Front

What is the formula for the area of a rhombus?

Back

The area of a rhombus can be calculated using the formula: Area = (d1 * d2) / 2, where d1 and d2 are the lengths of the diagonals.
