MCP Mathematics- Grade 3 geometry
Math vocabulary for grade 3 as presented in MCP math book.
Plane figures like squares and triangles
An angle that has less of an opening than a right angle
A triangle with 3 acute angles
A figure formed by two rays that have the same endpoint; the endpoint is called the vertex
A plane figure with 5 sides
A plane figure with 6 sides
A plane figure with 8 sides
The number of square units it takes to cover the surface of a plane figure
Line of symmetry
Divides a figure into 2 parts so that both parts match exactly
Flat surface on a pyramid, cube or prism.
The number of cubic units it takes to fill a solid figure
A position in space
Part of a line with 2 endpoints
Part of a line.....1 endpoint
Line that goes across
A line that goes up and down
Lines that meet at 1 point
Lins that do not intersect in the same plane, or flat surface
An angle that forms a square corner
Has a greater opening than a fit angle but less than a straight line
Lines, line segments or rays that form right angles
2 rays that have a common endpoint
Common endpoint of an angle
All sides same length
At least 2 sides are the same length
None of the sides are the same length
1 angle is a right angle
All 3 angles are acute angles
1 angle is an obtuse angle
Quad means 4- four sides and 4 angles
Opposite sides are parallel and all sides are the same length
1 pair of parallel sides only
4 right angles and opposite sides are the same length
4 right angles and all sides are the same length
Opposite sides are parallel a nd the same length .
"the same"- plane figures that are the same size and shape are called congruent figures
Moves a figure a given distance and a given direction. Another name for slide is a translation.
A flip moves a figure over a line to get a mirror image. Another name for a flip is a reflection.
A turn rotates a figure clockwise or counterclockwise. Another name for a turn is a rotation.
Moving a figure in a slide, flip or turn without changing its shape or size.
