Study Notes
Quadrilaterals Overview
- A quadrilateral is a four-sided polygon with various classifications based on side lengths and angle measures.
Parallelograms
- A parallelogram has both pairs of opposite sides parallel.
- A rhombus is a special type of parallelogram with four congruent sides.
- A rectangle is a parallelogram characterized by having four right angles.
- A square is a parallelogram that possesses both four congruent sides and four right angles.
Other Quadrilaterals
- A kite has two pairs of adjacent sides that are congruent, but no opposite sides are congruent.
- A trapezoid features exactly one pair of parallel sides.
- An isosceles trapezoid is a type of trapezoid where the nonparallel opposite sides are congruent.
Specific Terminology
- Consecutive angles are angles of a polygon that share a common side.
- The midsegment of a trapezoid connects the midpoints of the two parallel sides.
- Base angles are the two angles that share a base in a trapezoid.
