Study Notes
Quadrilaterals
- A rhombus has all sides congruent, exhibiting symmetry in its structure.
- A square is a special type of rhombus with all angles congruent (90 degrees).
- A rectangle is a quadrilateral with all angles being right angles and opposite sides equal; it can also be considered a specific type of parallelogram.
- A parallelogram features two pairs of parallel sides, and opposite sides are congruent.
- A trapezoid has one pair of parallel sides and can never have both all angles and all sides congruent.
Triangles
- An isosceles triangle has two sides that are congruent, giving it an axis of symmetry.
- An obtuse triangle contains one obtuse angle (greater than 90 degrees) along with two acute angles (less than 90 degrees).
- A right triangle consists of one right angle (90 degrees) and two other angles that can be acute.
Polygons
- A hexagon is defined as a polygon with 6 sides.
- A pentagon has 5 sides and is the next polygon with more complexity after the quadrilateral.
- An octagon is an 8-sided polygon; a regular octagon has all sides and angles congruent, creating a highly symmetrical figure.
Angle Types in Geometry
- Acute angles measure less than 90 degrees, while obtuse angles measure more than 90 degrees.
- In geometry, figures can be classified based on the types of angles they contain, as seen in various triangle classifications.
