Unit 5 Flashcards
Acute triangle
Triangle that contains only angles that are less than 90°
Angle
The amount of rotation needed to bring one line or plane into coincided with another generally measured in radians or degrees
Area
The number of square units required to cover surface
Axis
An imaginary line through the body about which it rotates. an imaginary line about which a regular figure is symmetrically arranged. A fixed reference line for the measurement of coordinates
Center of gravity
A 3-D point where the total weight of the body may be considered to be concentrated
Centroid
A 3-D point Defining the geometric center of a solid
Circle
A round plane figure whose boundary consists of points equidistant from the center
Circumscribe
A triangle located around a polygon
Cylinder
A solid comprised of two congruent circles in parallel planes their interiors and all the line segments parallel to the axis with in point on the two circles
Density
The measure of mass density is a measure of mass Per volume
Diameter
A straight line passing from side to side through the center of a circle or sphere
Ellipse
A shape generated by a point moving any plane so that the sum of its distances from two other points is constant and equal to the major axis
Fillet
A curve formed at the interior intersection between two or more surfaces
Inscribe
To draw a figure within another so that their boundaries touch but do not intersect
Mass
The amount of matter in an object or the quantity idea inertia of the object
Meniscus
The curved Upper surface of the liquid column that is concave when the containing walls are wetted by the liquid and convex when not
Obtuse triangle
A triangle with one angle that is greater than 90°
Parallelogram
A four sided polygon with both pairs of opposite sides parallel
Pi
The numerical value of the ratio of the circumference of the circle to its diameter
Polygon
Any plane figure bound by straight lines
Principal axes
The lines of intersection created from three mutually perpendicular planes
Prism
A solid geometric figure whose chill in our similar equal and have Parallel rectangular figures And whose sides are parallelograms
Quadrilateral
If four sided polygon
Radius
A straight line from the center to the circumference of a circle
Rectangle
A parallelogram with 90° angles
Regular polygon
A polygon with equal angles and equal sides
Right triangle
A triangle with 90° angle
Round
Two or more exterior surfaces rounded at their intersections
Square
A regular polygon with four equal sides and 4 90° angles
Surface area
A squared dimensions of the exterior surface
Tangent
A straight or curved line that intersects a circle or art at one point only
Title block
A table located in the bottom right-hand corner of an engineering drawing that Identifies in a Are ghettoized way all of the necessary information that is not given on the drawing itself
Triangle
Polygon with three sides
Vertex
Each angular point of a polygon
Volume
The amount of 3-D space occupied by object Or enclosed with in a container
