Geometry Chapter 8 Flashcards

Parallelogram

• Opposite sides are congruent.
• Both pairs of opposite sides are parallel.
• Diagonals bisect each other, creating congruent segments.

Rectangle

• Opposite sides are congruent and parallel.
• All angles are congruent (right angles).
• Diagonals are congruent and bisect each other.

Rhombus

• All sides are congruent, maintaining equal length.
• Opposite sides are both congruent and parallel.
• Diagonals intersect at right angles (perpendicular) and bisect each other.

Square

• All sides are congruent, and both sides are parallel.
• All angles are congruent (right angles).
• Diagonals are both congruent and perpendicular, bisecting each other.

Kite

• Has exactly one pair of opposite angles that are congruent.
• Diagonals are perpendicular to each other.
• Diagonals bisect one of the pairs of opposite angles.

Trapezoid

• Features exactly one pair of opposite sides that are parallel.

Midsegment Theorem

• The length of the midsegment (the segment connecting the midpoints of the non-parallel sides) is calculated using the formula: (B1 + B2) / 2, where B1 and B2 are the lengths of the two bases.

Know Two Go Two

• A formula used to find the number of sides or the measure of exterior angles in a regular polygon, expressed as: an = 360.
