Study Notes
Angles and Triangles
- Acute Angle: Measures greater than 0 degrees and less than 90 degrees.
- Acute Triangle: Contains three acute angles.
- Obtuse Angle: Measures greater than 90 degrees but less than 180 degrees.
- Obtuse Triangle: Has one obtuse angle.
- Right Angle: Measures exactly 90 degrees.
- Right Triangle: Contains one right angle.
- Complementary Angles: Two angles whose measures sum to 90 degrees.
- Supplementary Angles: Two angles whose measures sum to 180 degrees.
- Isosceles Triangle: Has two congruent sides and angles.
- Equilateral Triangle: All sides and angles are congruent.
- Scalene Triangle: No congruent sides; all sides are of different lengths.
Geometric Figures
- Cone: A three-dimensional figure with a curved surface and a circular base.
- Cylinder: Consists of two parallel, congruent circular bases connected by a curved surface.
- Pyramid: Has at least three triangular lateral faces and only one base.
- Prism: A three-dimensional figure with at least three rectangular lateral faces and parallel top and bottom faces.
- Polyhedron: A solid with four or more flat surfaces made of polygonal regions.
Lines and Angles
- Adjacent Angles: Share the same vertex and a common side without overlapping.
- Vertical Angles: Opposite angles formed by the intersection of two lines; they are congruent.
- Diagonal: A line segment connecting two nonconsecutive vertices of a polygon.
- Edge: The line segment where two faces of a three-dimensional figure meet.
- Skew Lines: Lines that do not intersect and are not coplanar.
Mathematical Concepts
- Bases: The top and bottom faces of a geometric figure.
- Scale: A ratio comparing the measures of a drawing or model to a real object.
- Scale Drawing: Represents objects that are too large or small to be drawn at actual size.
- Scale Factor: A ratio without units in simplest form, expressed in a multiplication context.
- Cross Section: The intersection of a solid with a plane.
Surfaces and Points
- Face: A flat surface forming a side or base of a prism.
- Vertex: The common endpoint of angle rays or the point where three or more planes intersect.
- Coplanar: Lines or points that lie in the same plane.
