Quadrilaterals and Their Properties Quiz

A quadrilateral with opposite sides parallel and equal.

In a parallelogram, if the diagonals are equal, it is a rectangle.

A rectangle has four right angles (90° each).

The sum of interior angles in a quadrilateral is 360°.

Triangles that are identical in size and shape; three parts must be equal.

If three sides of one triangle are equal to three sides of another, they are congruent.

If two sides and the included angle of one triangle equal two sides and the included angle of another triangle, they are congruent.

If two angles and the intervening side of one triangle are equal to two angles and the corresponding side of another, they are congruent.

Angles opposite each other when two lines intersect; they are always equal.

Two angles whose sum is 90°.

Two angles whose sum is 180°.

A square has all sides equal, four right angles, and diagonals that bisect each other at 90°.

The diagonals of a square are equal and bisect each other at right angles.

A line that divides an angle into two equal parts.

A parallelogram with one right angle is a rectangle.

A quadrilateral with all four sides equal is a rhombus.

A line that intersects two or more lines at different points.

Angles formed inside a polygon by its sides.

Certain angles can be equal, supplementary, or complementary based on their position.

Common quadrilaterals include squares, rectangles, rhombuses, and trapezoids.

A line from the center of a circle to any point on the circle is a radius.

A line that divides a segment into two equal parts at a right angle.

Angles on opposite sides of a transversal that lie inside the two lines.

If a = b and b = c, then a = c.

Points that are the same distance from two other points.

Finding a complementary angle to reach 90°.

Base times height; A = b × h.

A square’s area is side length squared; A = s².

The diagonal of a square can be calculated using A² + A² = d².

A rhombus has equal sides, opposite angles equal, and diagonals bisect each other at 90°.

Area can also be calculated with diagonals; A = (d1 × d2)/2.

In a right triangle, a² + b² = c², where c is the hypotenuse.

A shape is symmetric if it looks the same when divided by a line.
